Maxim Korotkov d86d698925 pinctrl: single: Fix potential division by zero ... [ Upstream commit 64c150339e ] There is a possibility of dividing by zero due to the pcs->bits_per_pin if pcs->fmask() also has a value of zero and called fls from asm-generic/bitops/builtin-fls.h or arch/x86/include/asm/bitops.h. The function pcs_probe() has the branch that assigned to fmask 0 before pcs_allocate_pin_table() was called Found by Linux Verification Center (linuxtesting.org) with SVACE.
