X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=73de3592c0da2313b25bac7789e9ea02c4b9f082;p=openwrt%2Fstaging%2Fblogic.git V4L/DVB (13828): uvcvideo: Make the quirks module parameter override the built-in quirks The quirks module parameter is or'ed with the built-in quirks for the device being probed. This make it impossible to disable a built-in quirk without recompiling the driver. Replace the built-in quirks with the quirks module parameter instead of or'ing the values.
