without this fix, a kernel compiled with imx_v4_v5_defconfig and running on a cpuimx25sd leads to : asoc: tlv320aic23-hifi <-> imx-ssi.0 mapping ok ------------[ cut here ]------------ WARNING: at fs/sysfs/dir.c:481 sysfs_add_one+0x90/0xb8() sysfs: cannot create duplicate filename '/devices/platform/soc-audio' Modules linked in: [<c00198e8>] (unwind_backtrace+0x0/0xf0) from [<c002ea5c>] (warn_slowpath_common+0x48/0x60) [<c002ea5c>] (warn_slowpath_common+0x48/0x60) from [<c002eb08>] (warn_slowpath_fmt+0x30/0x40) [<c002eb08>] (warn_slowpath_fmt+0x30/0x40) from [<c0120090>] (sysfs_add_one+0x90/0xb8) [<c0120090>] (sysfs_add_one+0x90/0xb8) from [<c0120118>] (create_dir+0x60/0xc0) [<c0120118>] (create_dir+0x60/0xc0) from [<c0120228>] (sysfs_create_dir+0x84/0xcc) [<c0120228>] (sysfs_create_dir+0x84/0xcc) from [<c019b9e0>] (kobject_add_internal+0xac/0x1d0) [<c019b9e0>] (kobject_add_internal+0xac/0x1d0) from [<c019bdd8>] (kobject_add+0x50/0x98) [<c019bdd8>] (kobject_add+0x50/0x98) from [<c01f6aec>] (device_add+0xb0/0x610) [<c01f6aec>] (device_add+0xb0/0x610) from [<c01fac8c>] (platform_device_add+0xfc/0x238) [<c01fac8c>] (platform_device_add+0xfc/0x238) from [<c046d884>] (mx27vis_aic32x4_init+0x38/0x84) [<c046d884>] (mx27vis_aic32x4_init+0x38/0x84) from [<c00088a0>] (do_one_initcall+0x34/0x178) [<c00088a0>] (do_one_initcall+0x34/0x178) from [<c045978c>] (kernel_init+0x78/0x114) [<c045978c>] (kernel_init+0x78/0x114) from [<c0014df4>] (kernel_thread_exit+0x0/0x8) ---[ end trace b6a96897e189aea3 ]--- kobject_add_internal failed for soc-audio with -EEXIST, don't try to register things with the same name in the same directory.
