Subject: sh_eth: reuse sh_eth_chip_reset()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c66b2581123cd1527b6a084f39e9271cb02673b7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

sh_eth: reuse sh_eth_chip_reset()

All the chip_reset() methods repeat the code writing to the ARSTR register
and delaying for 1 ms, so that we can reuse sh_eth_chip_reset() twice.
