ath10k: htt_rx: fix signedness bug in ath10k_update_per_peer_tx_stats
Currently, the error handling for the call to function ath10k_get_legacy_rate_idx() doesn't work because *rate_idx* is of type u8 (8 bits, unsigned), which makes it impossible for it to hold a value less than 0. Fix this by changing the type of variable *rate_idx* to s8 (8 bits, signed). Addresses-Coverity-ID: 1473914 ("Unsigned compared against 0") Fixes: 0189dbd71cbd ("ath10k: get the legacy rate index to update the txrate table") Signed-off-by: Gustavo A. R.
