[PATCH -next] mmc: sdhci-of-dwcmshc: fix error return code in dwcmshc_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

Fix to return negative error code -ENOMEM from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: c2c4da37837e ("mmc: sdhci-of-dwcmshc: add rockchip platform support")
