Subject: net: stmmac: Make 'alloc_dma_[rt]x_desc_resources()' look even closer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6224226030da93c062621527fd0070be3f718a88;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

net: stmmac: Make 'alloc_dma_[rt]x_desc_resources()' look even closer

'alloc_dma_[rt]x_desc_resources()' functions look very close.
Remove a useless initialization and use the same label name for error
handling path in order to get them even closer.
