Assuming it's enabled\n");I was doing the final pass before applying and I think that this is not quite correct, as it does not handle -EPROBE_DEFER properly which is quite common. I think we should do something like this: error = PTR_ERR(kp->clk); if (error != -ENOENT) { if (error != -EPROBE_DEFER) dev_err(.. "Failed to get clock" ...); return error; } dev_dbg(... "No clock specified" ...); No need to resubmit if you are OK with this, I can make the change locally.
Hmm, also bcm_kp_start() and bcm_kp_stop() should check if kp->clk is valid before trying to enable/disable it.
