libcamera: v4l2_device: Fix variable-sized object initialization
Compiling with clang renders errors as a variable-sized arrays are not allowed to be initialized. Solve this by using memset() for v4l2Ctrls which is the only one of the two arrays that needs to be zeroed. ../../src/libcamera/v4l2_device.cpp:155:37: error: variable-sized object may not be initialized const V4L2ControlInfo *controlInfo[count] = {}; ^~~~~ ../../src/libcamera/v4l2_device.cpp:156:36: error: variable-sized object may not be initialized struct v4l2_ext_control v4l2Ctrls[count] = {}; ^~~~~ ../../src/libcamera/v4l2_device.cpp:227:37: error: variable-sized object may not be initialized const V4L2ControlInfo *controlInfo[count] = {}; ^~~~~ ../../src/libcamera/v4l2_device.cpp:228:36: error: variable-sized object may not be initialized struct v4l2_ext_control v4l2Ctrls[count] = {}; ^~~~~ Fixes: eb068f4e67eedacd ("libcamera: v4l2_device: Implement get and set controls") Signed-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org>
