2008-10-21V4L/DVB (9300): pvrusb2: Fix deadlock problemMike Isely
Fix deadlock problem in 2.6.27 caused by new USB core behavior in response to a USB device reset request. With older kernels, the USB device reset was "in line"; the reset simply took place and the driver retained its association with the hardware. However now this reset triggers a disconnect, and worse still the disconnect callback happens in the context of the caller who asked for the device reset. This results in an attempt by the pvrusb2 driver to recursively take a mutex it already has, which deadlocks the driver's worker thread. (Even if the disconnect callback were to happen on a different thread we'd still have problems however - because while the driver should survive and correctly disconnect / reconnect, it will then trigger another device reset during the repeated initialization, which will then cause another disconect, etc, forever.) The fix here is simply to not attempt the device reset (it was of marginal value anyway). Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-10-21V4L/DVB (9299): cx18: Don't mask many real init error codes by mapping them ↵Andy Walls
to ENOMEM Changes to let error return codes bubble up to the user visible error message on card initialization. A number of them were being remapped to ENOMEM when no memory or array resource shortage existed. That hampered diagnosis of user trouble reports.

2008-10-21[PATCH] beginning of methods conversionAl Viro
To keep the size of changesets sane we split the switch by drivers; to keep the damn thing bisectable we do the following: 1) rename the affected methods, add ones with correct prototypes, make (few) callers handle both. That's this changeset. 2) for each driver convert to new methods. *ALL* drivers are converted in this series. 3) kill the old (renamed) methods. Note that it _is_ a flagday; all in-tree drivers are converted and by the end of this series no trace of old methods remain. The only reason why we do that this way is to keep the damn thing bisectable and allow per-driver debugging if anything goes wrong. New methods: open(bdev, mode) release(disk, mode) ioctl(bdev, mode, cmd, arg) /* Called without BKL */ compat_ioctl(bdev, mode, cmd, arg) locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */ Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
