[PATCH v3 1/7] gpio: davinci: coding style correction

Lad, Prabhakar prabhakar.csengg at gmail.com
Sun Aug 18 01:18:57 EDT 2013


From: Philip Avinash <avinashphilip at ti.com>

Make some minor coding style fixes. Use proper multi-line
commenting style, arrange include files alphabetically and
use a macro for register offset.

[nsekhar at ti.com: dropped changes which were considered
churn - line break fixes and variable name changes]
