commit fb239c1209 upstream.
In _rtl92c_get_txpower_writeval_by_regulatory() the variable writeVal
is assigned to itself in an if ... else statement, apparently only to
document that the branch condition is handled and that a previously read
value should be returned unmodified. The self-assignment causes clang to
raise the following warning:
drivers/net/wireless/realtek/rtlwifi/rtl8192cu/rf.c:304:13:
error: explicitly assigning value of variable of type 'u32'
(aka 'unsigned int') to itself [-Werror,-Wself-assign]
writeVal = writeVal;
Delete the branch with the self-assignment.
