From f0a7a2d042807d08e5bcfd3194e74b16810c4def Mon Sep 17 00:00:00 2001 From: Levente Kurusa Date: Thu, 19 Dec 2013 16:03:26 +0100 Subject: MIPS: TXx9: 7segled: add missing put_device call This is required so that we give up the last reference to the device. Also, add a new tx_7segled_release function which will be called after the put_device to ensure that device is kfree'd. [ralf@linux-mips.org: Reformat to Linux coding style and make tx_7segled_release static.] Signed-off-by: Levente Kurusa Cc: LKML Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/6260/ Signed-off-by: Ralf Baechle --- arch/mips/txx9/generic/7segled.c | 14 +++++++++++--- 1 file changed, 11 insertions(+), 3 deletions(-) diff --git a/arch/mips/txx9/generic/7segled.c b/arch/mips/txx9/generic/7segled.c index 4642f56e70e5..566c58bd44d0 100644 --- a/arch/mips/txx9/generic/7segled.c +++ b/arch/mips/txx9/generic/7segled.c @@ -83,6 +83,11 @@ static struct bus_type tx_7segled_subsys = { .dev_name = "7segled", }; +static void tx_7segled_release(struct device *dev) +{ + kfree(dev); +} + static int __init tx_7segled_init_sysfs(void) { int error, i; @@ -103,11 +108,14 @@ static int __init tx_7segled_init_sysfs(void) } dev->id = i; dev->bus = &tx_7segled_subsys; + dev->release = &tx_7segled_release; error = device_register(dev); - if (!error) { - device_create_file(dev, &dev_attr_ascii); - device_create_file(dev, &dev_attr_raw); + if (error) { + put_device(dev); + return error; } + device_create_file(dev, &dev_attr_ascii); + device_create_file(dev, &dev_attr_raw); } return error; } -- cgit v1.2.3
