[PATCH] mfd: syscon: free the allocated name field of struct regmap_config

map_config is need to be freed directly after regmap initialization to avoid memory leak. Fixes: 529a1101212a("mfd: syscon: Don't free allocated name for regmap_config") Cc: Marc Zyngier Cc: sta...@vger.kernel.org Signed-off-by: Meng Li --- drivers/mfd/syscon.c | 2 +- 1 file

[PATCH] drivers: spi: cadence: set cqspi to the driver_data field of struct device

From: Meng Li When initialize cadence qspi controller, it is need to set cqspi to the driver_data field of struct device, because it will be used in function cqspi_remove/suspend/resume(). Otherwise, there will be a crash trace as below when invoking these finctions. Call trace: cqspi_suspend

[PATCH] driver: regmap: set debugfs_name to NULL after it is freed

From: Meng Li There is a upstream commit cffa4b2122f5("regmap:debugfs: Fix a memory leak when calling regmap_attach_dev") that adds a if condition when create name for debugfs_name. With below function invoking logical, debugfs_name is freed in regmap_debugfs_exit(), but it is not cre
