      ASoC: cs42l51: fix driver to properly autoload with automatic module loading · e51df4f8
      Thomas Petazzoni authored
      In commit 2cb1e025 ("ASoC: cs42l51: re-hook of_match_table
      pointer"), 9 years ago, some random guy fixed the cs42l51 after it was
      split into a core part and an I2C part to properly match based on a
      Device Tree compatible string.
      
      However, the fix in this commit is wrong: the MODULE_DEVICE_TABLE(of,
      ....) is in the core part of the driver, not the I2C part. Therefore,
      automatic module loading based on module.alias, based on matching with
      the DT compatible string, loads the core part of the driver, but not
      the I2C part. And threfore, the i2c_driver is not registered, and the
      codec is not known to the system, nor matched with a DT node with the
      corresponding compatible string.
      
      In order to fix that, we move the MODULE_DEVICE_TABLE(of, ...) into
      the I2C part of the driver. The cs42l51_of_match[] array is also moved
      as well, as it is not possible to have this definition in one file,
      and the MODULE_DEVICE_TABLE(of, ...) invocation in another file, due
      to how MODULE_DEVICE_TABLE works.
      
      Thanks to this commit, the I2C part of the driver now properly
      autoloads, and thanks to its dependency on the core part, the core
      part gets autoloaded as well, resulting in a functional sound card
      without having to manually load kernel modules.

            size and corrupt data.
      
          - Revert "tracing: Add "(fault)" name injection to kernel probes"

            function itself, instead of store_trace_args(). If we record an

      Pull x86 CFI fixes from Peter Zijlstra:
       "Fix kCFI/FineIBT weaknesses
      
        The primary bug Alyssa noticed was that with FineIBT enabled function
        prologues have a spurious ENDBR instruction:
      
          __cfi_foo:
      	endbr64
      	subl	$hash, %r10d
      	jz	1f
      	ud2
      	nop
          1:
          foo:
      	endbr64 <--- *sadface*
      
        This means that any indirect call that fails to target the __cfi
        symbol and instead targets (the regular old) foo+0, will succeed due
        to that second ENDBR.
      
        Fixing this led to the discovery of a single indirect call that was
        still doing this: ret_from_fork(). Since that's an assembly stub the
        compiler would not generate the proper kCFI indirect call magic and it
        would not get patched.
      
        Brian came up with the most comprehensive fix -- convert the thing to
        C with only a very thin asm wrapper. This ensures the kernel thread
        boostrap is a proper kCFI call.
      
        While discussing all this, Kees noted that kCFI hashes could/should be
        poisoned to seal all functions whose address is never taken, further
        limiting the valid kCFI targets -- much like we already do for IBT.
      
        So what was a 'simple' observation and fix cascaded into a bunch of
        inter-related CFI infrastructure fixes"

      Pull tracing fixes from Steven Rostedt:
      
       - Fix some missing-prototype warnings
      
       - Fix user events struct args (did not include size of struct)
      
         When creating a user event, the "struct" keyword is to denote that
         the size of the field will be passed in. But the parsing failed to
         handle this case.
      
       - Add selftest to struct sizes for user events
      
       - Fix sample code for direct trampolines.
      
         The sample code for direct trampolines attached to handle_mm_fault().
         But the prototype changed and the direct trampoline sample code was
         not updated. Direct trampolines needs to have the arguments correct
         otherwise it can fail or crash the system.
      
       - Remove unused ftrace_regs_caller_ret() prototype.
      
       - Quiet false positive of FORTIFY_SOURCE
      
         Due to backward compatibility, the structure used to save stack
         traces in the kernel had a fixed size of 8. This structure is
         exported to user space via the tracing format file. A change was made
         to allow more than 8 functions to be recorded, and user space now
         uses the size field to know how many functions are actually in the
         stack.
      
         But the structure still has size of 8 (even though it points into the
         ring buffer that has the required amount allocated to hold a full
         stack.
      
         This was fine until the fortifier noticed that the
         memcpy(&entry->caller, stack, size) was greater than the 8 functions
         and would complain at runtime about it.
      
         Hide this by using a pointer to the stack location on the ring buffer
         instead of using the address of the entry structure caller field.
      
       - Fix a deadloop in reading trace_pipe that was caused by a mismatch
         between ring_buffer_empty() returning false which then asked to read
         the data, but the read code uses rb_num_of_entries() that returned
         zero, and causing a infinite "retry".
      
       - Fix a warning caused by not using all pages allocated to store ftrace
         functions, where this can happen if the linker inserts a bunch of
         "NULL" entries, causing the accounting of how many pages needed to be
         off.
      
       - Fix histogram synthetic event crashing when the start event is
         removed and the end event is still using a variable from it
      
       - Fix memory leak in freeing iter->temp in tracing_release_pipe()
