      mtd: dc21285: use raw spinlock functions for nw_gpio_lock · e5babdf9
      由 Uwe Kleine-König 提交于 
      Since commit bd31b859 (which is in 3.2-rc1) nw_gpio_lock is a raw spinlock
that needs usage of the corresponding raw functions.

This fixes:

      mtd: chips: fixup dependencies, to prevent build error · bde90062
      由 Brian Norris 提交于 
      Commit 4612c715 ("mtd: cfi: deinline large functions") moved some
code into the cfi_util library without creating a new dependency. So we
can get build failures like the following, when CONFIG_MTD_JEDECPROBE=y
and CONFIG_MTD_CFI_UTIL=m.

   drivers/built-in.o: In function `jedec_read_id':
>> jedec_probe.c:(.text+0x187ed8): undefined reference to `cfi_build_cmd_addr'

   drivers/built-in.o:jedec_probe.c:(.text+0x188511): more undefined references to `cfi_send_gen_cmd' follow
   drivers/built-in.o: In function `jedec_probe_chip':
>> jedec_probe.c:(.text+0x188618): undefined reference to `cfi_build_cmd'

So let's express the dependency properly.

      firmware: dmi_scan: Fix ordering of product_uuid · 5c1ac56b
      由 Jean Delvare 提交于 
      In function dmi_present(), dmi_walk_early() calls dmi_table(), which
calls dmi_decode(), which ultimately calls dmi_save_uuid(). This last
function makes a decision based on the value of global variable
dmi_ver. The problem is that this variable is set right _after_
dmi_walk_early() returns. So dmi_save_uuid() always sees dmi_ver == 0
regardless of the actual version implemented.

This causes /sys/class/dmi/id/product_uuid to always use the old
ordering even on systems implementing DMI/SMBIOS 2.6 or later, which
should use the new ordering.

This is broken since kernel v3.8 for legacy DMI implementations and
since kernel v3.10 for SMBIOS 2 implementations. SMBIOS 3
implementations with the 64-bit entry point are not affected.

The first breakage does not matter much as in practice legacy DMI
implementations are always for versions older than 2.6, which is when
the UUID ordering changed. The second breakage is more problematic as
it affects the vast majority of x86 systems manufactured since 2009.

      firmware: dmi_scan: Simplified displayed version · c2493045
      由 Jean Delvare 提交于 
      The trailing .x adds no information for the reader, and if anyone
tries to parse that line, this is more work as they have 3 different
formats to handle instead of 2. Plus, this makes backporting fixes
harder.
