Subject: arch/nios2/include/asm/irqflags.h:12:9: sparse: sparse: context
imbalance in 'snd_pcm_group_unlock_irq' - unexpected unlock
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 916a3b0fc1206f7e7ae8d00a21a3114b1dc67794
commit: 80591e61a0f7e88deaada69844e4a31280c4a38f kbuild: tell sparse about the $ARCH
date: 8 months ago
config: nios2-randconfig-s032-20200628 (attached as .config)
compiler: nios2-linux-gcc (GCC) 9.3.0
reproduce:
# apt-get install sparse
# sparse version: v0.6.2-dirty
git checkout 80591e61a0f7e88deaada69844e4a31280c4a38f
# save the attached .config to linux build tree
make W=1 C=1 ARCH=nios2 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'
