Hi
I just found out that the commit bfdbfd28f76028b960458d107dc4ae9240c928b3
which also went in the stable release series causes an oops
in the stmicro driver an a Terrasic DE0 NanoSoc board with Intel SocFPGA
CycloneV chip. I am currently following Preempt-RT that's why i just noticed
only yet when testing 5.4.10-rt5 but this also occurs without any Preempt-RT
patchset. Reverting the patch fixes the oops.
It would be nice if this change could be reverted or otherwise fixed.
Best regards
Tim Sander

This should be fixed with:
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=da29f2d84bd10234df570b7f07cbd0166e738230
which will likely make it so stable soon.
