Subject: ASoC: codecs: tlv320dac33: Add default value for burst_bclkdiv
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=960ef523cfe420ae8fdd801f1d12be0fb7ed8719;p=users%2Fhch%2Fmisc.git

ASoC: codecs: tlv320dac33: Add default value for burst_bclkdiv

Add default value for field burst_bclkdiv as initializing it to 0
is incorrect, potentially leading to a divide by 0 issue.
Valid range is 2-17 per TI datasheet. 8 was chosen as a
dummy value.
