2014-11-22ALSA: asihpi: Refactor control cache code.Eliot Blennerhassett1-44/+63
Signed-off-by: Eliot Blennerhassett <eliot@blennerhassett.gen.nz> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-12-22ALSA: asihpi - Correct headers in cached control responses.Eliot Blennerhassett1-1/+7
Previously, only payload and size were correct, sufficient for reading, but other fields produced spurious debug output. Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-12-22ALSA: asihpi - Remove redundant struct members.Eliot Blennerhassett1-10/+10
Structs hpi_adapter and snd_card_asihpi had members that duplicate those in underlying hpi_adapter_obj or whose info can be retrieved using hpi_adapter_get_info(). Print less info in probe function, it can be retrieved from /proc. Avoid name redundancy: hpi_adapter_obj.adapter_type renamed to .type Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-12-06ALSA: asihp: Use kcalloc instead of kzalloc to allocate arrayThomas Meyer1-1/+1
The advantage of kcalloc is, that will prevent integer overflows which could result from the multiplication of number of elements and size and it is also a bit nicer to read. The semantic patch that makes this change is available in https://lkml.org/lkml/2011/11/25/107 Signed-off-by: Thomas Meyer <thomas@m3y3r.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-08-07ALSA: asihpi - use kzalloc()Thomas Meyer1-3/+2
Use kzalloc rather than kmalloc followed by memset with 0 This considers some simple cases that are common and easy to validate Note in particular that there are no ...s in the rule, so all of the matched code has to be contiguous The semantic patch that makes this output is available in scripts/coccinelle/api/alloc/kzalloc-simple.cocci.

2010-11-02ALSA: asihpi - Unsafe memory management when allocating control cacheJesper Juhl1-3/+9
I noticed that sound/pci/asihpi/hpicmn.c::hpi_alloc_control_cache() does not check the return value from kmalloc(), which may fail. If kmalloc() fails we'll dereference a null pointer and things will go bad fast. There are two memory allocations in that function and there's also the problem that the first may succeed and the second may fail and nothing is done about that either which will also go wrong down the line.
