The final patch removes the unplug/replug deadlock by not holding the device
mutex during dvb_init(). However, this mutex has already been locked during
device initialisation by em28xx_usb_probe() and is not released again until all
extensions have been initialised successfully.
The device mut
This patch closes the race on the device and extension lists at USB disconnect
time. Previously, the device was removed from the device list during
em28xx_release_resources(), and then passed to the em28xx_close_extension()
function so that all extensions could run their fini() operations. Howev
Next patch: By default, the DVB framework tries to put a frontend to sleep after
it has been shut down. This obviously doesn't work for a USB device that has
been disconnected, and can result in occasional errors in dmesg about I2C writes
failing with error code -19.
The patch works by nulling
Two more patches:
a) clean up resources more reliably if em28xx_init_dev() fails,
b) move two printk() statements outside the mutex lock

Hi,
Here's my latest patch for the em28xx / em28xx-dvb modules, which addresses the
following problems:
a) Locking problem when unplugging and then replugging USB adapter.
b) Race conditions between adding/removing devices from the devlist, while
simultaneously loading/unloading extension mod
