[PATCH v1 1/1] ufs: mcq: qcom: Clean the return path of ufs_qcom_mcq_config_resource

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

 



Smatch static checker reported:
drivers/ufs/host/ufs-qcom.c:1469
ufs_qcom_mcq_config_resource() info: returning a literal zero is
cleaner

Fix the above warning by returning in place instead of a jump to a
label.
Also remove the usage of devm_kfree() as it's unnecessary in this
function.

Fixes: c263b4ef737e ("scsi: ufs: core: mcq: Configure resource regions")
