Merge tag 'scmi-fixes-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/fixes
ARM SCMI fixes for v5.14 A small set of fixes: - adding check for presence of probe while registering the driver to prevent NULL pointer access - dropping the duplicate check as the driver core already takes care of it - fix for possible scmi_linux_errmap buffer overflow - fix to avoid sensor message structure padding - fix the range check for the maximum number of pending SCMI messages - fix for various kernel-doc warnings * tag 'scmi-fixes-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Fix range check for the maximum number of pending messages firmware: arm_scmi: Avoid padding in sensor message structure firmware: arm_scmi: Fix kernel doc warnings about return values firmware: arm_scpi: Fix kernel doc warnings firmware: arm_scmi: Fix kernel doc warnings firmware: arm_scmi: Fix possible scmi_linux_errmap buffer overflow firmware: arm_scmi: Ensure drivers provide a probe function firmware: arm_scmi: Simplify device probe function on the bus Link: https://lore.kernel.org/r/20210714165831.2617437-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>
