Subject: [media] cx231xx: use TRANSFER_TYPE enum for cleanup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=460a4de77d3b8f82fce98a9ed10e10464f767f97;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[media] cx231xx: use TRANSFER_TYPE enum for cleanup

Most calls to cx231xx_capture_start() already use the values from
TRANSFER_TYPE, but cx231xx_capture_start() and
cx231xx_initialize_stream_xfer() were hand coding the values.
Use the named values (81 is never passed in), and simplify
cx231xx_capture_start(), as the switch statements were identical and
pcb_config->config_num is a u8, so any non-zero config got the same
result.
