[PATCH 1/7] firmware: cs_dsp: Fix error checking in wseq_write()

[Fred Treven <ftreven@opensource.cirrus.com>]

cs_dsp_coeff_write_ctrl() may return a non-zero value (1)
upon success. Change error checking in the write sequencer
code such that it checks for negative errnos rather than
any non-zero value when using this function.
