void v4l2_m2m_clear_state (struct v4l2_m2m_ctx *m2m_ctx );
not me pointing out the tiny space before that closing paren π it's in the original, we respect the original, we do NOT touch it π«Ά
πΈ ARGUMENTS πΈ
m2m_ctxβ the m2m context that's been assigned to the instance, given to us bystruct v4l2_m2m_ctx. it's giving "this is the thing you hand me so i can do the thing" energy π
π SEE ALSO π
bestie the guest list for this function's birthday party is LONG and honestly iconic. also peep the kernel file ./include/media/v4l2-mem2mem.h because that's where the whole family lives π β¨
