Subject: device create: dca: convert device_create to device_create_drvdata
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=275e64decc01acf4d2f6b6ad1b83f1c4bd9033e5;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

device create: dca: convert device_create to device_create_drvdata

device_create() is race-prone, so use the race-free
device_create_drvdata() instead as device_create() is going away.
