mt7601u: make write with mask access atomic Introduce __mt7601u_rr and __mt7601u_vendor_single_wr routines in order to make mt7601u_rmw and mt7601u_rmc atomic. This patch does not fix a reported issue but makes the usb access more robust to concurrent operations on the same register since it is theoretically possible that read and write accesses of mt7601u_rmw/mt7601u_rmc can be interleaved with a different write operation on the same register. Moreover using __mt7601u_rr and __mt7601u_vendor_single_wr in mt7601u_rmw/mt7601u_rmc allows to grab vendor_req_mutex mutex once instead of twice Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Acked-by: Jakub Kicinski <kubakici@wp.pl> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
