fbdev: mmp: Fix deferred clk handling in mmphw_probe()

Browse source

[ Upstream commit b3a7a9ab65 ]

When dev_err_probe() is called, 'ret' holds the value of the previous
successful devm_request_irq() call.
'ret' should be assigned with a meaningful value before being used in
dev_err_probe().

While at it, use and return "PTR_ERR(ctrl->clk)" instead of a hard-coded
"-ENOENT" so that -EPROBE_DEFER is handled and propagated correctly.
