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.
