Subject: via-velocity: add velocity_set_rxbufsize helper
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9088d9a4267ff098d5edc3dad8359c92741b7a6a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

via-velocity: add velocity_set_rxbufsize helper

It removes a dependancy from velocity_init_rd_ring to dev->mtu.
