clang points out a possible corner case in the mt7915_tm_set_tx_cont()
function if called with invalid arguments:
drivers/net/wireless/mediatek/mt76/mt7915/testmode.c:593:2: warning: variable 'mode' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized]
default:
^~~~~~~
drivers/net/wireless/mediatek/mt76/mt7915/testmode.c:597:13: note: uninitialized use occurs here
rateval = mode << 6 | rate_idx;
^~~~
drivers/net/wireless/mediatek/mt76/mt7915/testmode.c:506:37: note: initialize the variable 'mode' to silence this warning
u8 rate_idx = td->tx_rate_idx, mode;
^
Change it to return an error instead of continuing with invalid data
here.
