[PATCH v2] staging: sm750fb: style fixes: align call and split chained assignment
Posted by Cristian Del Gobbo 3 months, 1 week ago
- Drop previous change that made g_fbmode[] elements const (broke build).
- Align the continued arguments of sm750_hw_cursor_set_size() with the
  opening parenthesis.
- Replace a chained assignment of red/green/blue with a temporary
  variable to satisfy checkpatch and improve readability.

No functional change intended.

This patch was really confusing because I had no idea what I reported.
Just remove my reported by tag...

This is not a v2 patch, it's a whole new patch.  Don't call it a v2.

But if it were a v2, this isn't the right way to send a v2.  In a v2 this
would go under the --- cut off line.

These are unrelated changes.  Do them as separate patches.

Also run your patch through checkpatch.pl.

y is a strange variable name.  It has nothing to do with the y axis.
