Xiaolei Wang 480c5e9c7e regmap: debugfs: Fix a memory leak when calling regmap_attach_dev ... commit cffa4b2122 upstream. After initializing the regmap through syscon_regmap_lookup_by_compatible, then regmap_attach_dev to the device, because the debugfs_name has been allocated, there is no need to redistribute it again unreferenced object 0xd8399b80 (size 64): comm "swapper/0", pid 1, jiffies 4294937641 (age 278.590s) hex dump (first 32 bytes): 64 75 6d 6d 79 2d 69 6f 6d 75 78 63 2d 67 70 72 dummy-iomuxc-gpr 40 32 30 65 34 30 30 30 00 7f 52 5b d8 7e 42 69 @20e4000..R[.~Bi backtrace: [<ca384d6f>] kasprintf+0x2c/0x54 [<6ad3bbc2>] regmap_debugfs_init+0xdc/0x2fc [<bc4181da>] __regmap_init+0xc38/0xd88 [<1f7e0609>] of_syscon_register+0x168/0x294 [<735e8766>] device_node_get_regmap+0x6c/0x98 [<d96c8982>] imx6ul_init_machine+0x20/0x88 [<0456565b>] customize_machine+0x1c/0x30 [<d07393d8>] do_one_initcall+0x80/0x3ac [<7e584867>] kernel_init_freeable+0x170/0x1f0 [<80074741>] kernel_init+0x8/0x120 [<285d6f28>] ret_from_fork+0x14/0x20 [<00000000>] 0x0 Fixes: 9b947a13e7 ("regmap: use debugfs even when no device") Signed-off-by: Xiaolei Wang <xiaolei.wang@windriver.com> Link: https://lore.kernel.org/r/20201229105046.41984-1-xiaolei.wang@windriver.com Signed-off-by: Mark Brown <broonie@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2021-01-17 14:05:37 +01:00
