Date: Tue, 27 Mar 2012 10:08:25 +0800 From: Axel Lin <axel.lin@...il.com> To: linux-kernel@...r.kernel.org Cc: Sonic Zhang <sonic.zhang@...log.com>, Liam Girdwood <lrg@...com>, Mark Brown <broonie@...nsource.wolfsonmicro.com> Subject: [PATCH 1/2] regulator: ad5398: show changing current in uA Integer division may truncate the result. Current code shows changing current is 0mA when selector is 1 ... 8. For example: selector = 1 ad5398_calc_current returns 117, debug message shows 117/1000 = 0mA selector = 2 ad5398_calc_current returns 234, debug message shows 234/1000 = 0mA selector = 3 ad5398_calc_current returns 351, debug message shows 351/1000 = 0mA ............ selector = 8 ad5398_calc_current returns 937, debug message shows 937/1000 = 0mA Show the changing current in uA makes it easier for debugging.
