[PATCH v2 net-next 0/8] net: phy: fix some coding-style issues

[Weihang Li]

Make some cleanups according to the coding style of kernel.

Changes since v1:
- Update commit description of #1 and #3.
- Avoid changing the indentation in #2.
- Change a group of if-else statement into switch from #4 and put it into
  a single patch.
- Put '|' at the end of line in #5 and #7.
- Avoid deleting spaces in definition of 'settings' in #5.
- Drop #8 from the series which needs more discussion with David.

Weihang Li (1):
  net: phy: replace if-else statements with switch

Wenpeng Liang (7):
  net: phy: change format of some declarations
  net: phy: correct format of block comments
  net: phy: delete repeated words of comments
  net: phy: fix space alignment issues
  net: phy: fix formatting issues with braces
  net: phy: print the function name by __func__ instead of an fixed
    string
  net: phy: remove unnecessary line continuation

[Weihang Li]
