[PATCH 6.1] soc: ti: omap_prm: Add a null pointer check to the omap_prm_domain_init

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

 



[ Upstream commit 5d7f58ee08434a33340f75ac7ac5071eea9673b3 ]

devm_kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure. Ensure the allocation was successful
by checking the pointer validity.
