fbdev: mmp: Fix deferred clk handling in mmphw_probe()
[ Upstream commit b3a7a9a ] 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. Fixes: 81b6342 ("fbdev: mmp: Make use of the helper function dev_err_probe()") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Sasha Levin <sashal@kernel.org>
