[v11,02/19] drm: bridge: analogix/dp: fix some obvious code style

Commit Message

Yakir Yang Dec. 16, 2015, 3:26 a.m. UTC

Fix some obvious alignment problems, like alignment and line
over 80 characters problems, make this easy to be maintained
later.

- Resequence this patch after analogix_dp driver have been split
  from exynos_dp code, and rephrase reasonable commit message, and
  remove some controversial style (Krzysztof)
    -		analogix_dp_write_byte_to_dpcd(

Changes in v2:
- Improved commit message more readable, and avoid using some

    -  retval = exynos_dp_read_bytes_from_i2c(...
  				  ...);
    +  retval =
