[PATCH] mt76: Fix an IS_ERR() vs NULL check in mt76_wmac_probe()

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

 



The devm_ioremap_resource() function never returns NULL, it returns
error pointers.

Fixes: c8846e101502 ("mt76: add driver for MT7603E and MT7628/7688")
