Subject: ALSA: snd-usb: handle the bmFormats field as unsigned int
X-Git-Tag: upstream/snapshot3+hdmi~5112^2~96
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2fcdb06d4919da89ed6d52742dcc83ae4669ac30;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

ALSA: snd-usb: handle the bmFormats field as unsigned int

This field may use up to 32 bits, so it should be handled as unsigned
int.
