Prev: [PATCH] RTC/max6900: use rtc_valid_tm to check returning tm for max6900
Next: firewire: core: no need to track irq flags in bm_work
From: Datta, Shubhrajyoti on 22 Jun 2010 05:20
Updates for the BMP085 pressure sensor
- Optimizing the wait time for the pressure sensor
- Definition of long is arch dependent so making it u32.
