      spi: bitbang: Let spi_bitbang_start() take a reference to master · 94c69f76
      Axel Lin authored
      Many drivers that use bitbang library have a leak on probe error paths.
      This is because once a spi_master_get() call succeeds, we need an additional
      spi_master_put() call to free the memory.
      
      Fix this issue by moving the code taking a reference to master to
      spi_bitbang_start(), so spi_bitbang_start() will take a reference to master on
      success. With this change, the caller is responsible for calling
      spi_bitbang_stop() to decrement the reference and spi_master_put() as
      counterpart of spi_alloc_master() to prevent a memory leak.
      
      So now we have below patten for drivers using bitbang library:
      
      probe:
      spi_alloc_master        -> Init reference count to 1
      spi_bitbang_start       -> Increment reference count
      remove:
      spi_bitbang_stop        -> Decrement reference count
      spi_master_put          -> Decrement reference count (reference count reaches 0)
      
      Fixup all users accordingly.

      partitions/efi: loosen check fot pmbr size in lba · 6b02fa59
      Davidlohr Bueso authored
      Matt found that commit 27a7c642 ("partitions/efi: account for pmbr
      size in lba") caused his GPT formatted eMMC device not to boot.  The
      reason is that this commit enforced Linux to always check the lesser of
      the whole disk or 2Tib for the pMBR size in LBA.  While most disk
      partitioning tools out there create a pMBR with these characteristics,
      Microsoft does not, as it always sets the entry to the maximum 32-bit
      limitation - even though a drive may be smaller than that[1].
      
      Loosen this check and only verify that the size is either the whole disk
      or 0xFFFFFFFF.  No tool in its right mind would set it to any value
      other than these.
