If anyone has any objections, please let me know. ------------------ From: Max Gurtovoy [ Upstream commit ca2770c65b56374374fa00c349883e67c16943de ] The following changes were made: 1. Align function signatures to 80 characters per line. 2. Remove tabs for variable assignment and use 1 space instead. 3. Don't compare to NULL in "if" clause. 4. Remove strange indentations. This will ease on the maintenance of the driver for the future.
