Subject: [PATCH] sym53c500_cs: remove bogus call fo free_dma()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9a696b4f3c5664c2c4815cc8e37256e51a3425e1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] sym53c500_cs: remove bogus call fo free_dma()

What DMA for 16bit pcmcia card, anyway?  We never do request_dma()
there and ->dma_channel never changes since initialization to -1.
IOW, that call is dead code.
