2014-07-24staging/goldfish/goldfish_audio: fix a sparse warningRobin Schroer1-1/+1
Fix a pointer check to use NULL instead of 0 Warning: drivers/staging/goldfish/goldfish_audio.c:300:34: warning: Using plain integer as NULL pointer Signed-off-by: Robin Schroer <sulamiification@gmail.com> Acked-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-07-09staging: goldfish: Introduce the use of managed interfacesHimangi Saraogi1-40/+13
This patch introduces the use of managed interfaces like devm_kzalloc, devm_ioremap, dmam_alloc_coherent, devm_request_irq and does away with the calls to functions to free the allocated memory in the probe and remove functions. Also, the labels are removed in the probe function.

2014-05-16goldfish_nand.c: remove length restrictionsNick Kralevich1-4/+0
Remove limitations on the size of a read / write request. AFAIK, there's no consequence to allowing the upper layers to specify different read / write sizes. This is needed to support running ext4 on goldfish.

2014-04-16staging: goldfish: Call free_irq in error pathTuomas Tynkkynen1-0/+1
If misc_register failed in goldfish_audio_probe, the already requested IRQ wouldn't get freed. Add a call to free_irq() like there is in goldfish_audio_remove().

2013-12-17staging: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.
