commit: d6064165ba4449ea085a389724d728258a3180ec [43/49] crypto: qat - adf_dev_stop should not be called in atomic context
config: i386-allmodconfig (attached as .config)
reproduce:
git checkout d6064165ba4449ea085a389724d728258a3180ec
# save the attached .config to linux build tree
make ARCH=i386

>> WARNING: drivers/crypto/qat/qat_common/intel_qat.o(.init.text+0x30d): Section mismatch in reference from the function init_module() to the function .exit.text:adf_exit_vf_wq()
The function __init init_module() references
a function __exit adf_exit_vf_wq().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __exit annotation of
adf_exit_vf_wq() so it may be used outside an exit section.

Is it still complaining even after this?
