Subject: Fix error checking in Vitesse IRQ config
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=52cb1c2b70d9d2a81e842b90456b7a8158541ffd;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Fix error checking in Vitesse IRQ config

phy_read() returns a negative number if there's an error, but the
error-checking code in the Vitesse driver's config_intr function
triggers if phy_read() returns non-zero.  Correct that.
