From 7ebcf26c39205ca8d61c178dcd3f5be4f25b1309 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Wed, 16 Sep 2015 12:10:26 -0700 Subject: [PATCH] regulator: core: Make error messages more informative The same error print exists 4 times in the regulator core : operation not allowed Unfortunately, seeing this in the dmesg is not very informative. Add what type of operation is not allowed to the message so that these errors are unique, hopefully pointing developers in the right direction : drms operation not allowed : voltage operation not allowed : current operation not allowed : mode operation not allowed Signed-off-by: Stephen Boyd Signed-off-by: Mark Brown --- drivers/regulator/core.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/regulator/core.c b/drivers/regulator/core.c index 7a85ac9e32c5..065fe877dcf5 100644 --- a/drivers/regulator/core.c +++ b/drivers/regulator/core.c @@ -180,7 +180,7 @@ static int regulator_check_voltage(struct regulator_dev *rdev, return -ENODEV; } if (!(rdev->constraints->valid_ops_mask & REGULATOR_CHANGE_VOLTAGE)) { - rdev_err(rdev, "operation not allowed\n"); + rdev_err(rdev, "voltage operation not allowed\n"); return -EPERM; } @@ -240,7 +240,7 @@ static int regulator_check_current_limit(struct regulator_dev *rdev, return -ENODEV; } if (!(rdev->constraints->valid_ops_mask & REGULATOR_CHANGE_CURRENT)) { - rdev_err(rdev, "operation not allowed\n"); + rdev_err(rdev, "current operation not allowed\n"); return -EPERM; } @@ -277,7 +277,7 @@ static int regulator_mode_constrain(struct regulator_dev *rdev, int *mode) return -ENODEV; } if (!(rdev->constraints->valid_ops_mask & REGULATOR_CHANGE_MODE)) { - rdev_err(rdev, "operation not allowed\n"); + rdev_err(rdev, "mode operation not allowed\n"); return -EPERM; } @@ -301,7 +301,7 @@ static int regulator_check_drms(struct regulator_dev *rdev) return -ENODEV; } if (!(rdev->constraints->valid_ops_mask & REGULATOR_CHANGE_DRMS)) { - rdev_dbg(rdev, "operation not allowed\n"); + rdev_dbg(rdev, "drms operation not allowed\n"); return -EPERM; } return 0; -- 2.20.1
