Subject: ASoC: tas5805m: Use devm_kmemdup to replace devm_kmalloc + memcpy
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=b0a4c7f5921d9c2998bdd767a93d995786d72adc;p=tomoyo%2Ftomoyo-test1.git

ASoC: tas5805m: Use devm_kmemdup to replace devm_kmalloc + memcpy

Use the helper function devm_kmemdup() rather than duplicating its
implementation, which helps to enhance code readability.
