Subject: [PATCH 0/2] firmware: cs_dsp: Remove usage of GFP_DMA
Also drop the bounce buffer in cs_dsp_coeff_write_ctrl_raw().
The bounce buffer in cs_dsp_coeff_write_ctrl_raw() could theoretically
also be removed. That would be a functional change as the output may be
modified in error cases.
As I don't know the driver very well I left that part out.
Not tested on real hardware.
This came up while porting kunit to mips64.
Apparently GFP_DMA does not work there, but IMO the usage of GFP_DMA by
cs_dsp is unnecessary in the first place.
