If clk_get() returns -ENOENT, there is no need to defer the driver, -ENOENT will be returned the same for each retries. So, return the error code directly instead of -EPROBE_DEFER.
Remove this special case and use dev_err_probe() to simplify code. It will also be less verbose if the clk is really deferred.
Fixes: 47cbea216281 ("ASoC: Intel: eve: Enable mclk and ssp sclk early") Signed-off-by: Christophe JAILLET christophe.jaillet@wanadoo.fr --- This is based on my understanding of clk_get(). Review with care.
Not sure the Fixes tag is needed. The patch does not fix anything. If devm_clk_get() returns -ENOENT, it will just loop several time until the framework gives up. If it returns -EPROBE_DEFER, this case is already handled by the "return ret;"
So this patch should be a no-op, just a clean-up. --- .../intel/boards/kbl_rt5663_rt5514_max98927.c | 31 ++++--------------- 1 file changed, 6 insertions(+), 25 deletions(-)
