commit c8e57e1b766c2321aa76ee5e6878c69bd2313d62 upstream.

Failure to allocate the I/O region leaves the IRQ allocated.
A later failure leaves them both allocated.

media: staging: lirc_serial: Fix init/exit order

2012-03-12T17:33:00+00:00

commit 9105b8b200410383d0854bbe237ee385d7d33ba6 upstream.

Currently the module init function registers a platform_device and
only then allocates its IRQ and I/O region.  This allows allocation to
race with the device's suspend() function.  Instead, allocate
resources in the platform driver's probe() function and free them in
the remove() function.

The module exit function removes the platform device before the
character device that provides access to it.  Change it to reverse the
order of initialisation.

Staging: asus_oled: fix NULL-ptr crash on unloading

2012-02-13T19:06:12+00:00

commit 3589e74595a4332ebf77b5ed006f3c6686071ecd upstream.

Asus_oled triggers the following bug on module unloading:

 usbcore: deregistering interface driver asus-oled

This is due to an incorrect destruction sequence in asus_oled_exit().

Fix the order, fixes the bug. Tested on an Asus G50V laptop only.

Staging: asus_oled: fix image processing

2012-02-13T19:06:12+00:00

commit 635032cb397b396241372fa0ff36ae758e658b23 upstream.

Programming an image was broken, because odev->buf_offs was not advanced
for val == 0 in append_values(). This regression was introduced in:

     Staging: asus_oled: Cleaned up checkpatch issues.

Fix the image processing by special-casing val == 0.

I have tested this change on an Asus G50V laptop only.

Staging: comedi: fix mmap_count

2011-12-09T16:52:40+00:00

commit df30b21cb0eed5ba8a8e0cdfeebc66ba8cde821d upstream.

In comedi_fops, mmap_count is decremented at comedi_vm_ops->close but
it is not incremented at comedi_vm_ops->open. This may result in a negative
counter.  The patch introduces the open method to keep the counter
consistent.

The bug was triggerd by this sample code:

        mmap(0, ...., comedi_fd);
        fork();
        exit(0);
