Subject: powerpc/mv643xx_eth: fix return check in mv64x60_eth_register_shared_pdev()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dde8e3ee6b37fa33690604302bebfe7b576c3802;p=linux-beck.git

powerpc/mv643xx_eth: fix return check in mv64x60_eth_register_shared_pdev()

In case of error, the function platform_device_register_simple() returns
RR_PTR() and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().
