[PATCH -next] remoteproc: imx_rproc: fix return value check in imx_rproc_addr_init()

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

 



From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

In case of error, the function devm_ioremap() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should
be replaced with NULL test.

Fixes: ecadcc47492c ("remoteproc: imx_rproc: use devm_ioremap")
