Subject: mv_xor: fix race in tasklet function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8333f65ef094e47020cd01452b4637e7daf5a77f;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

mv_xor: fix race in tasklet function

use mv_xor_slot_cleanup() instead of __mv_xor_slot_cleanup() as the former function
aquires the spin lock that needed to protect the drivers data.
