James Clark 09f222d40f coresight: etm4x: Fix width of CCITMIN field ... commit cc0271a339 upstream. CCITMIN is a 12 bit field and doesn't fit in a u8, so extend it to u16. This probably wasn't an issue previously because values higher than 255 never occurred. But since commit 4aff040bcc ("coresight: etm: Override TRCIDR3.CCITMIN on errata affected cpus"), a comparison with 256 was done to enable the errata, generating the following W=1 build error: coresight-etm4x-core.c:1188:24: error: result of comparison of constant 256 with expression of type 'u8' (aka 'unsigned char') is always false [-Werror,-Wtautological-constant-out-of-range-compare] if (drvdata->ccitmin == 256) Cc: stable@vger.kernel.org Fixes: 2e1cdfe184 ("coresight-etm4x: Adding CoreSight ETM4x driver") Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202310302043.as36UFED-lkp@intel.com/ Reviewed-by: Mike Leach <mike.leach@linaro.org> Signed-off-by: James Clark <james.clark@arm.com> Signed-off-by: Suzuki K Poulose <suzuki.poulose@arm.com> Link: https://lore.kernel.org/r/20231101115206.70810-1-james.clark@arm.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2024-01-20 11:51:49 +01:00
