v4l2: Document expected fallthrough
Compilers may now enable warnings for implicit fallthrough of switch
case statements, to help catch errors. One such case is highlighted in
our v4l2 module:
v4l2.c: In function ‘v4l2_enum_frame_sizes’:
v4l2.c:179:23: warning: this statement may fall through [-Wimplicit-fallthrough=]
frame->step_height = frmenum.stepwise.step_height;
~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
v4l2.c:180:3: note: here
case V4L2_FRMSIZE_TYPE_CONTINUOUS:
^~~~
This fall through is expected, and the warning can be removed simply by
adding a comment to confirm that.
