ASoC: max98090: make REVISION_ID readable
The REVISION_ID register is not currently marked readable. snd_soc_read() refuses to read the register, and hence probe() fails. Fixes: d4807ad2c4c0 ("regmap: Check readable regs in _regmap_read") [exposed the bug, by checking for readability] Fixes: 685e42154dcf ("ASoC: Replace max98090 Device Driver") [left out this register from the readable list] Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org>
