[alsa-devel] [PATCH 1/2] ASoC: rt5514: Fix rt5514_spi_burst_read() buffer passing

rt5514_dsp_voice_wake_up_put() passes "(u8 *)&buf" to
rt5514_spi_burst_read(), where the cast is needed to silence a compiler
warning:
sound/soc/codecs/rt5514.c: In function ‘rt5514_dsp_voice_wake_up_put’:
sound/soc/codecs/rt5514.c:357: warning: passing argument 2 of ‘rt5514_spi_burst_read’ from incompatible pointer type
However, as the variable is declared as an array ("u8 buf[8]"), the
function should just pass "buf" instead.
Fixes: fc9cab05837639ce ("ASoC: rt5514: The DSP clock can be calibrated by the other clock source")
