Subject: [PATCH net-next 1/1] net: pcs: xpcs: fix error handling on failed to allocate memory
Date: Tue, 10 Aug 2021 16:58:12 +0800 [thread overview]
Message-ID: <20210810085812.1808466-1-vee.khee.wong@linux.intel.com> (raw)
Drivers such as sja1105 and stmmac that call xpcs_create() expects an
error returned by the pcs-xpcs module, but this was not the case on
failed to allocate memory.
Fixed this by returning an -ENOMEM instead of a NULL pointer.
