regmap: Fix debugfs-file 'registers' mode

2014-09-29T17:22:26Z

The macro "REGMAP_ALLOW_WRITE_DEBUGFS" can be used to enable write support on the registers file in the debugfs. The mode of the file is fixed to 0400 so it is not possible to write the file ever. This patch fixes the mode by setting it to the correct value depending on the macro. Signed-off-by: Markus Pargmann Signed-off-by: Mark Brown

regmap: fix possible ZERO_SIZE_PTR pointer dereferencing error.

2014-09-28T10:55:07Z

Since we cannot make sure the 'val_count' will always be none zero here, and then if it equals to zero, the kmemdup() will return ZERO_SIZE_PTR, which equals to ((void *)16). So this patch fix this with just doing the zero check before calling kmemdup(). Signed-off-by: Xiubo Li Signed-off-by: Mark Brown Cc: stable@vger.kernel.org

regmap: debugfs: fix possbile NULL pointer dereference

2014-09-28T10:49:56Z

If 'map->dev' is NULL and there will lead dev_name() to be NULL pointer dereference. So before dev_name(), we need to have check of the map->dev pionter. We also should make sure that the 'name' pointer shouldn't be NULL for debugfs_create_dir(). So here using one default "dummy" debugfs name when the 'name' pointer and 'map->dev' are both NULL.

regmap: fix NULL pointer dereference in _regmap_write/read

2014-09-27T11:21:15Z

If LOG_DEVICE is defined and map->dev is NULL it will lead to NULL pointer dereference. This patch fixes this issue by adding check for dev->NULL in all such places in regmap.c Signed-off-by: Pankaj Dubey Signed-off-by: Mark Brown Cc: stable@vger.kernel.org

regmap: fix NULL pointer dereference in regmap_get_val_endian

2014-09-18T17:55:31Z

Recents commits for getting reg endianness causing NULL pointer dereference if dev is passed NULL in regmap_init_mmio. This patch fixes this issue, and allows to parse reg endianness only if dev and dev->of_node exist. Signed-off-by: Pankaj Dubey Signed-off-by: Mark Brown
