Subject: net: microchip: sparx5: Update return value check for vcap_get_rule()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=95b358e4d9c7caad3a787f810265458ee477d0ef;p=linux.git

net: microchip: sparx5: Update return value check for vcap_get_rule()

As Simon Horman suggests, update vcap_get_rule() to always
return an ERR_PTR() and update the error detection conditions to
use IS_ERR(), so use IS_ERR() to check the return value.
