From: Hans Verkuil Date: Wed, 16 Apr 2014 12:41:25 +0000 (-0300) Subject: [media] v4l2-ctrls: increase internal min/max/step/def to 64 bit X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0ba2aeb6dab80920edd9cf5b93b1ea4d6913b8f3;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [media] v4l2-ctrls: increase internal min/max/step/def to 64 bit While VIDIOC_QUERYCTRL is limited to 32 bit min/max/step/def values for controls, the upcoming VIDIOC_QUERY_EXT_CTRL isn't. So increase the internal representation to 64 bits in preparation. Because of these changes the msi3101 driver has been modified slightly to fix a formatting issue (%d becomes %lld), vivi had to be modified as well to cope with the new 64-bit min/max values and the PIXEL_RATE control in a few sensor drivers required proper min/max/def values.
