Subject[linux-stable-rc:linux-5.14.y 717/2116] drivers/mmc/host/wbsd.c:212:28: error: implicit declaration of function 'claim_dma_lock'
Hi Arnd,

First bad commit (maybe != root cause):

tree: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git linux-5.14.y
head: 3dfa869cb79d60a2fe66efb4a11517ec7c89de16
commit: 3afd2af53a59327caf21aaadbf5c9b6f3fc0117b [717/2116] m68knommu: only set CONFIG_ISA_DMA_API for ColdFire sub-arch
config: m68k-randconfig-r021-20210927 (attached as .config)
compiler: m68k-linux-gcc (GCC) 11.2.0
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/commit/?id=3afd2af53a59327caf21aaadbf5c9b6f3fc0117b
git remote add linux-stable-rc https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git
git fetch --no-tags linux-stable-rc linux-5.14.y
git checkout 3afd2af53a59327caf21aaadbf5c9b6f3fc0117b
# save the attached .config to linux build tree
