Subject: [PATCH 11/14] drivers/net/wireless/atmel.c: Use time_* macros
The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values.
So following patch implements usage of the time_after() macro, defined at linux/jiffies.h, which deals with wrapping correctly
