[PATCH] staging: rts5208: Added value check

From: Denis Arefev
Date: Fri Nov 18 2022 - 06:15:32 EST


Added value check.
Return value of a function 'ms_set_rw_reg_addr'
called at ms.c:1770 is not checked,
but it is usually checked for this function

Found by Linux Verification Center (linuxtesting.org) with SVACE.
