staging: Remove unnecessary OOM messages

2013-02-11T18:10:33+00:00

alloc failures already get standardized OOM
messages and a dump_stack.

For the affected mallocs around these OOM messages:

Converted kzallocs with multiplies to kcalloc.
Converted kmallocs with multiplies to kmalloc_array.
Converted a kmalloc/strlen/strncpy to kstrdup.
Moved a spin_lock below a removed OOM message and
removed a now unnecessary spin_unlock.
Neatened alignment and whitespace.

staging: asus_oled: Change printk calls to dev_xxx

2012-08-15T22:31:26+00:00

- Use dev_err whenever a struct device * is present
- None of the printk calls had levels set, but looked like they should
  probably be dev_err

USB: asus_oled.c: remove err() usage

2012-04-20T23:53:17+00:00

err() was a very old USB-specific macro that I thought had
gone away.  This patch removes it from being used in the
driver and uses dev_err() instead.

Documentation: remove references to /etc/modprobe.conf

2012-03-30T23:03:15+00:00

Usage of /etc/modprobe.conf file was deprecated by module-init-tools and
is no longer parsed by new kmod tool. References to this file are
replaced in Documentation, comments and Kconfig according to the
context.

There are also some references to the old /etc/modules.conf from 2.4
kernels that are being removed.

staging: asus_oled: Remove superfluous loop

2012-02-29T23:43:21+00:00

This patch removes a superfluous loop in asus_oled.c
The code is equivalent to do{...} while (0) and thus executes the code
exactly once -> so we can simply remove the loop.

Staging: asus_oled: fix NULL-ptr crash on unloading

2012-02-08T22:14:13+00:00

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

2012-02-08T22:14:13+00:00

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

 commit 1ff12a4aa354bed093a0240d5e6347b1e27601bc
 Author: Kevin A. Granade 
 Date:   Sat Sep 5 01:03:39 2009 -0500

     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.
