| |
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.
Signed-off-by: Matthias Kaehlcke <mka@chromium.org> --- Changes in v2: - Delete the 'else if' branch entirely
