[PATCH -next v2] input: touchscreen: mxs-lradc: Fix return value check in mxs_lradc_ts_probe()

[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(). Use devm_ioremap_resource() instead of devm_ioremap().

v1 -> v2: use devm_ioremap_resource()
