      spi: Check we have a spi_device_id for each DT compatible · 5fa6863b
      Mark Brown 提交于
      Currently for SPI devices we use the spi_device_id for module autoloading
      even on systems using device tree, meaning that listing a compatible string
      in the of_match_table isn't enough to have the module for a SPI driver
      autoloaded.
      
      We attempted to fix this by generating OF based modaliases for devices
      instantiated from DT in 3ce6c9e2 ("spi: add of_device_uevent_modalias
      support") but this meant we no longer reported spi_device_id based aliases
      which broke drivers such as spi-nor which don't list all the compatible
      strings they support directly for DT, and in at least that case it's not
      super practical to do so given the very large number of compatibles
      needed, much larger than the number spi_device_ids due to vendor strings.
      As a result fell back to using spi_device_id based modalises.
      
      Try to close the gap by printing a warning when a SPI driver has a DT
      compatible that won't be matched as a SPI device ID with the goal of having
      drivers provide both. Given fallback compatibles this check is going to be
      excessive but it should be robust which is probably more important here.

      perf tools: Allow build-id with trailing zeros · 4a86d414
      Namhyung Kim 提交于
      Currently perf saves a build-id with size but old versions assumes the
      size of 20.  In case the build-id is less than 20 (like for MD5), it'd
      fill the rest with 0s.
      
      I saw a problem when old version of perf record saved a binary in the
      build-id cache and new version of perf reads the data.  The symbols
      should be read from the build-id cache (as the path no longer has the
      same binary) but it failed due to mismatch in the build-id.
      
        symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf.
      
      The build-id event in the data has 20 byte build-ids, but it saw a
      different size (16) when it reads the build-id of the elf file in the
      build-id cache.
      
        $ readelf -n ~/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf
