X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=293c8513398657f6263fcdb03c87f2760cf61be4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

gianfar: Fix regression caused by new napi interface

Protect all new napi function calls with CONFIG_GFAR_NAPI.  Otherwise
the driver will stop working when CONFIG_GFAR_NAPI disabled.
