This patch matches the existing call to input_alloc_device() in da9052_ts_probe() to a new call to input_free_device() in da9052_ts_remove() Suggested-by: Huqiu Liu Signed-off-by: Anthony Olech --- This patch is relative to linux-next repository tag next-20140108 Many thanks to Huqiu Liu who found the bug. drivers/input/touchscreen/da9052_tsi.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/input/touchscreen/da9052_tsi.c b/drivers/input/touchscreen/da9052_tsi.c index ab64d58..43a69d1 100644 --- a/drivers/input/touchscreen/da9052_tsi.c +++ b/drivers/input/touchscreen/da9052_tsi.c @@ -320,6 +320,7 @@ err_free_mem: static int da9052_ts_remove(struct platform_device *pdev) { struct da9052_tsi *tsi = platform_get_drvdata(pdev); + struct input_dev *input_dev = tsi->dev; da9052_reg_write(tsi->da9052, DA9052_LDO9_REG, 0x19); @@ -328,6 +329,7 @@ static int da9052_ts_remove(struct platform_device *pdev) input_unregister_device(tsi->dev); kfree(tsi); + input_free_device(input_dev); return 0; } -- end-of-patch for input: fix memory leak in da9052 touchscreen driver V1
