[PATCH v2 1/1] mmc: sdhci-spear: Fix NULL pointer dereference

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

 



pdata could be NULL if cd_gpio = -1. Dereference pdata only
if it is not NULL.

Compile tested.
Changes since v1:
* Moved the pdata assignment inside if condition.
