Subject: libertas: fix memory corruption in lbs_remove_card()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=517ff43146b17a0d067125f098f675d1e0ac2d82;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

libertas: fix memory corruption in lbs_remove_card()

"priv" is stored at the end of the wiphy structure, which is freed
during the call to lbs_cfg_free(). It must not be touched afterwards.

Remove the unnecessary NULL assignment causing this memory corruption.
