From: Charles Keepax <ckeepax@opensource.cirrus.com> stable inclusion from stable-v5.10.124 commit 70e355867dc21bdc59d6835274077d3073ba423a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5L6E7 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 5005a2345825eb8346546d99bfe669f73111b5c5 ] The digital volume TLV specifies the step as 0.25dB but the actual step of the control is 0.125dB. Update the TLV to correct this. Signed-off-by: Charles Keepax <ckeepax@opensource.cirrus.com> Link: https://lore.kernel.org/r/20220602162119.3393857-3-ckeepax@opensource.cirrus...
