Ah yea, this error happens because in this commit: https://github.com/torvalds/linux/commit/8653d71ce3763aedcf3d2331f59beda3fecd79e4 the tasklets are replaced with works. Should I request the patch to be in v5.10 or should I update the fix to use queue_work(system_highpri_wq, &midi->work) ? > >> drivers/usb/gadget/function/f_midi.c:286:31: error: no member named 'tasklet' in 'struct f_midi' > 286 | tasklet_hi_schedule(&midi->tasklet); > | ~~~~ ^ > 1 error generated.
