commit aaeb61a97b upstream.
`pc236_detach()` is called by the comedi core if it attempted to attach
a device and failed. `pc236_detach()` calls `pc236_intr_disable()` if
the comedi device private data pointer (`devpriv`) is non-null. This
test is insufficient as `pc236_intr_disable()` accesses hardware
registers and the attach routine may have failed before it has saved
their I/O base addresses.
Fix it by checking `dev->iobase` is non-zero before calling
`pc236_intr_disable()` as that means the I/O base addresses have been
saved and the hardware registers can be accessed. It also implies the
comedi device private data pointer is valid, so there is no need to
check it.

commit c8cad4c89e upstream.
When `do_cmd_ioctl()` allocates memory for the kernel copy of a channel
list, it frees any previously allocated channel list in
`async->cmd.chanlist` and replaces it with the new one. However, if the
device is ever removed (or "detached") the cleanup code in
`cleanup_device()` in "drivers.c" does not free this memory so it is
lost.
A sensible place to free the kernel copy of the channel list is in
`do_become_nonbusy()` as at that point the comedi asynchronous command
associated with the channel list is no longer valid. Free the channel
list in `do_become_nonbusy()` instead of `do_cmd_ioctl()` and clear the
pointer to prevent it being freed more than once.
Note that `cleanup_device()` could be called at an inappropriate time
while the comedi device is open, but that's a separate bug not related
to this this patch.

commit 40fe4f8967 upstream.
softsynth_read() reads a character at a time from the init string;
when it finds the null terminator it sets the initialized flag but
then repeats the last character.
Additionally, if the read() buffer is not big enough for the init
string, the next read() will start reading from the beginning again.
So the caller may never progress to reading anything else.
Replace the simple initialized flag with the current position in
the init string, carried over between calls. Switch to reading
real data once this reaches the null terminator.
(This assumes that the length of the init string can't change, which
seems to be the case. Really, the string and position belong together
in a per-file private struct.)

Currently the module init function registers a platform_device and
only then allocates its IRQ and I/O region. This allows allocation to

The module exit function removes the platform device before the

However, this could result in a lost wakeup scenario due to a race
in the logic in the qt2_ioctl(TIOCMIWAIT) loop and the URB completion
for new modem status in qt2_process_modem_status.
Due to this, the usermode app's task will continue to sleep despite a

Fix the function not to iterate nodes when the scan is aborted. The nodes
are already freed when the module is being unloaded. Patch "ath6kl: Fix a

enough as a pointer was still used even after the null check. This patch
removes the null check entirely as the wmi structure is not accessed anymore
during module unload.

There's really no good reason not to just grab the desired IRQ at driver
init time, instead of every time the lirc device node is accessed. This
also improves the speed and reliability with which a serial transmitter
can operate, as back-to-back transmission attempts (i.e., channel change
to a multi-digit channel) don't have to spend time acquiring and then
releasing the IRQ for every digit, sometimes multiple times, if lircd
has been told to use the min_repeat parameter.
