A new warning in clang points out a few places in this driver where a bitwise OR is being used with boolean types: drivers/input/touchscreen.c:81:17: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical] data_present = touchscreen_get_prop_u32(dev, "touchscreen-min-x", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This use of a bitwise OR is intentional, as bitwise operations do not short circuit, which allows all the calls to touchscreen_get_prop_u32() to happen so that the last parameter is initialized while coalescing the results of the calls to make a decision after they are all evaluated. To make this clearer to the compiler, use the '|=' operator to assign the result of each touchscreen_get_prop_u32() call to data_present, which keeps the meaning of the code the same but makes it obvious that every one of these calls is expected to happen.

Uwe Kleine-König authored
On i.MX7S and i.MX8M* (but not i.MX6*) the pwrkey device has an associated clock. Accessing the registers requires that this clock is enabled. Binding the driver on at least i.MX7S and i.MX8MP while not having the clock enabled results in a complete hang of the machine. (This usually only happens if snvs_pwrkey is built as a module and the rtc-snvs driver isn't already bound because at bootup the required clk is on and only gets disabled when the clk framework disables unused clks late during boot.) This completes the fix in commit 135be16d ("ARM: dts: imx7s: add snvs clock to pwrkey").

I received a build failure for a new patch I'm working on the nds32 architecture, and when I went to test it, I couldn't get to my build error, because it failed to build with a bunch of: Error: invalid operands (*UND* and *UND* sections) for `^' issues with various files. Those files were temporary asm files that looked like: kernel/.tmp_mc_fork.s I decided to look deeper, and found that the "mc" portion of that name stood for "mcount", and was created by the recordmcount.pl script. One that I wrote over a decade ago. Once I knew the source of the problem, I was able to investigate it further. The way the recordmcount.pl script works (BTW, there's a C version that simply modifies the ELF object) is by doing an "objdump" on the object file. Looks for all the calls to "mcount", and creates an offset of those locations from some global variable it can use (usually a global function name, found with <.*>:). Creates a asm file that is a table of references to these locations, using the found variable/function. Compiles it and links it back into the original object file. This asm file is called ".tmp_mc_<object_base_name>.s". The problem here is that the objdump produced by the nds32 object file, contains things that look like: 0000159a <.L3^B1>: 159a: c6 00 beqz38 $r6, 159a <.L3^B1> 159a: R_NDS32_9_PCREL_RELA .text+0x159e 159c: 84 d2 movi55 $r6, #-14 159e: 80 06 mov55 $r0, $r6 15a0: ec 3c addi10.sp #0x3c Where ".L3^B1 is somehow selected as the "global" variable to index off of. Then the assembly file that holds the mcount locations looks like this: .section __mcount_loc,"a",@progbits .align 2 .long .L3^B1 + -5522 .long .L3^B1 + -5384 .long .L3^B1 + -5270 .long .L3^B1 + -5098 .long .L3^B1 + -4970 .long .L3^B1 + -4758 .long .L3^B1 + -4122 [...] And when it is compiled back to an object to link to the original object, the compile fails on the "^" symbol. Simple solution for now, is to have the perl script ignore using function symbols that have an "^" in the name.

gpr_get() return the entire pt_regs (include sr) to userspace, if we don't restore the C bit in gpr_set, it may break the ALU result in that context. So the C flag bit is part of gpr context, that's why riscv totally remove the C bit in the ISA. That makes sr reg clear from userspace to supervisor privilege.

csky restore_sigcontext() blindly overwrites regs->sr with the value it finds in sigcontext. Attacker can store whatever they want in there, which includes things like S-bit. Userland shouldn't be able to set that, or anything other than C flag (bit 0). Do the same thing other architectures with protected bits in flags register do - preserve everything that shouldn't be settable in user mode, picking the rest from the value saved is sigcontext.

Pull spi fixes from Mark Brown: "A few small fixes. Mostly driver specific but there's one in the core which fixes a deadlock when adding devices on spi-mux that's triggered because spi-mux is a SPI device which is itself a SPI controller and so can instantiate devices when registered. We were using a global lock to protect against reusing chip selects but they're a per controller thing so moving the lock per controller resolves that" * tag 'spi-fix-v5.15-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: spi-mux: Fix false-positive lockdep splats spi: Fix deadlock when adding SPI controllers on SPI buses spi: bcm-qspi: clear MSPI spifie interrupt during probe spi: spi-nxp-fspi: don't depend on a specific node name erratum workaround spi: mediatek: skip delays if they are 0 spi: atmel: Fix PDC transfer setup bug spi: spidev: Add SPI ID table spi: Use 'flash' node name instead of 'spi-flash' in example
