Message-Id: <1269094385-16114-17-git-send-email-w.sang@pengutronix.de> Date: Sat, 20 Mar 2010 15:12:57 +0100 From: Wolfram Sang <w.sang@...gutronix.de> To: kernel-janitors@...r.kernel.org Cc: linux-i2c@...r.kernel.org, linux-kernel@...r.kernel.org, Wolfram Sang <w.sang@...gutronix.de> Subject: [PATCH 16/24] power: fix dangling pointers Fix I2C-drivers which missed setting clientdata to NULL before freeing the structure it points to. Also fix drivers which do this _after_ the structure was freed already. Signed-off-by: Wolfram Sang <w.sang@...gutronix.de> --- Found using coccinelle, then reviewed. Full patchset is available via kernel-janitors, linux-i2c, and LKML. --- drivers/power/bq27x00_battery.c | 2 ++ 1 files changed, 2 insertions(+), 0 deletions(-) diff --git a/drivers/power/bq27x00_battery.c b/drivers/power/bq27x00_battery.c index bece33e..b909103 100644 --- a/drivers/power/bq27x00_battery.c +++ b/drivers/power/bq27x00_battery.c @@ -399,6 +399,7 @@ static int bq27x00_battery_probe(struct i2c_client *client, batt_failed_4: kfree(bus); + i2c_set_clientdata(client, NULL); batt_failed_3: kfree(di); batt_failed_2: @@ -423,6 +424,7 @@ static int bq27x00_battery_remove(struct i2c_client *client) idr_remove(&battery_id, di->id); mutex_unlock(&battery_mutex); + i2c_set_clientdata(client, NULL); kfree(di); return 0; -- 1.7.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
