ath10k: fix latency issue for QCA988x
(kvalo: cherry picked from commit 1340cc631bd00431e2f174525c971f119df9efa1 in wireless-drivers-next to wireless-drivers as this a frequently reported regression) Bad latency is found on QCA988x, the issue was introduced by commit 4504f0e5b571 ("ath10k: sdio: workaround firmware UART pin configuration bug"). If uart_pin_workaround is false, this change will set uart pin even if uart_print is false. Tested HW: QCA9880 Tested FW: 10.2.4-1.0-00037 Fixes: 4504f0e5b571 ("ath10k: sdio: workaround firmware UART pin configuration bug") Signed-off-by: Miaoqing Pan <miaoqing@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
