Allow more than one viperboard to be connected by registering with PLATFORM_DEVID_AUTO instead of PLATFORM_DEVID_NONE. The subdevices are currently registered with PLATFORM_DEVID_NONE, which will cause a name collision on the platform bus when a second viperboard is plugged in: viperboard 1-2.4:1.0: version 0.00 found at bus 001 address 004 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 181 at /home/johan/work/omicron/src/linux/fs/sysfs/dir.c:31 sysfs_warn_dup+0x74/0x84() sysfs: cannot create duplicate filename '/bus/platform/devices/viperboard-gpio' Modules linked in: i2c_viperboard viperboard netconsole [last unloaded: viperboard] CPU: 0 PID: 181 Comm: bash Tainted: G W 3.17.0-rc6 #1 [<c0016bf4>] (unwind_backtrace) from [<c0013860>] (show_stack+0x20/0x24) [<c0013860>] (show_stack) from [<c04305f8>] (dump_stack+0x24/0x28) [<c04305f8>] (dump_stack) from [<c0040fb4>] (warn_slowpath_common+0x80/0x98) [<c0040fb4>] (warn_slowpath_common) from [<c004100c>] (warn_slowpath_fmt+0x40/0x48) [<c004100c>] (warn_slowpath_fmt) from [<c016f1bc>] (sysfs_warn_dup+0x74/0x84) [<c016f1bc>] (sysfs_warn_dup) from [<c016f548>] (sysfs_do_create_link_sd.isra.2+0xcc/0xd0) [<c016f548>] (sysfs_do_create_link_sd.isra.2) from [<c016f588>] (sysfs_create_link+0x3c/0x48) [<c016f588>] (sysfs_create_link) from [<c02867ec>] (bus_add_device+0x12c/0x1e0) [<c02867ec>] (bus_add_device) from [<c0284820>] (device_add+0x410/0x584) [<c0284820>] (device_add) from [<c0289440>] (platform_device_add+0xd8/0x26c) [<c0289440>] (platform_device_add) from [<c02a5ae4>] (mfd_add_device+0x240/0x344) [<c02a5ae4>] (mfd_add_device) from [<c02a5ce0>] (mfd_add_devices+0xb8/0x110) [<c02a5ce0>] (mfd_add_devices) from [<bf00d1c8>] (vprbrd_probe+0x160/0x1b0 [viperboard]) [<bf00d1c8>] (vprbrd_probe [viperboard]) from [<c030c000>] (usb_probe_interface+0x1bc/0x2a8) [<c030c000>] (usb_probe_interface) from [<c028768c>] (driver_probe_device+0x14c/0x3ac) [<c028768c>] (driver_probe_device) from [<c02879e4>] (__driver_attach+0xa4/0xa8) [<c02879e4>] (__driver_attach) from [<c0285698>] (bus_for_each_dev+0x70/0xa4) [<c0285698>] (bus_for_each_dev) from [<c0287030>] (driver_attach+0x2c/0x30) [<c0287030>] (driver_attach) from [<c030a288>] (usb_store_new_id+0x170/0x1ac) [<c030a288>] (usb_store_new_id) from [<c030a2f8>] (new_id_store+0x34/0x3c) [<c030a2f8>] (new_id_store) from [<c02853ec>] (drv_attr_store+0x30/0x3c) [<c02853ec>] (drv_attr_store) from [<c016eaa8>] (sysfs_kf_write+0x5c/0x60) [<c016eaa8>] (sysfs_kf_write) from [<c016dc68>] (kernfs_fop_write+0xd4/0x194) [<c016dc68>] (kernfs_fop_write) from [<c010fe40>] (vfs_write+0xb4/0x1c0) [<c010fe40>] (vfs_write) from [<c01104a8>] (SyS_write+0x4c/0xa0) [<c01104a8>] (SyS_write) from [<c000f900>] (ret_fast_syscall+0x0/0x48) ---[ end trace 98e8603c22d65817 ]--- viperboard 1-2.4:1.0: Failed to add mfd devices to core. viperboard: probe of 1-2.4:1.0 failed with error -17 Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org> |
