Subject: ASoC: cs42l52: Use case range at appropriate place
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4caae9546d2cf7dbc7a12d451f847d7b58912bda;p=linux-beck.git

ASoC: cs42l52: Use case range at appropriate place

The readable registers are in continuous range: 0x01 ~ 0x34.
Use case range syntax makes the code shorter with better readability when
we have a large number of continuous switch cases.
No functional change with this patch.
