However cxl_adapter_context_get() wrongly compares # the return value against '>=0' which will always be true. The patch # fixes this comparison to '==0' there by also fixing this compile time # warning: # # drivers/misc/cxl/main.c:290 cxl_adapter_context_get() # warn: 'atomic_inc_unless_negative(&adapter->contexts_num)' is unsigned # # Fixes: 70b565bbdb91 ("cxl: Prevent adapter reset if an active context exists") # Cc: stable@vger.kernel.org # v4.9+ # Reported-by: Dan Carpenter # Signed-off-by: Vaibhav Jain # Acked-by: Andrew Donnellan # Acked-by: Frederic Barrat # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 7eeb18a4da1ebbdb8e9583aa28c2965584ad7dab # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc6xx_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/net/Makefile:24: CC cannot link executables.
