From 53cf9a605d75877550c1b9793d7e994401d08eb7 Mon Sep 17 00:00:00 2001 From: Amit Kucheria Date: Wed, 21 Oct 2009 14:49:22 +0300 Subject: [PATCH] mfd: Fix more undefined twl4030-power resconfig value checks Based on Aaro's previous fix, this needs to be fixed for the newly added remap_off and remap_sleep resources as well. The code tries to skip values initialized with -1, but since the values are unsigned the comparison is always true. The patch eliminates the following compiler warnings: drivers/mfd/twl4030-power.c: In function 'twl4030_configure_resource': drivers/mfd/twl4030-power.c:338: warning: comparison is always true due to limited range of data type Signed-off-by: Amit Kucheria Signed-off-by: Samuel Ortiz --- drivers/mfd/twl4030-power.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/mfd/twl4030-power.c b/drivers/mfd/twl4030-power.c index 9f98c36273d8..3048f18e0419 100644 --- a/drivers/mfd/twl4030-power.c +++ b/drivers/mfd/twl4030-power.c @@ -398,12 +398,12 @@ static int __init twl4030_configure_resource(struct twl4030_resconfig *rconfig) return err; } - if (rconfig->remap_off >= 0) { + if (rconfig->remap_off != TWL4030_RESCONFIG_UNDEF) { remap &= ~OFF_STATE_MASK; remap |= rconfig->remap_off << OFF_STATE_SHIFT; } - if (rconfig->remap_sleep >= 0) { + if (rconfig->remap_sleep != TWL4030_RESCONFIG_UNDEF) { remap &= ~SLEEP_STATE_MASK; remap |= rconfig->remap_off << SLEEP_STATE_SHIFT; } -- GitLab
