| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the first hunk, 0 is returned on memory allocation failure, even though other failures return -ENOMEM or other similar values. In the second hunk, there was error handling code that returned without freeing psz_path_name.

| | | | | | | | | | | | | | | | | | | | | | | | This driver uses ioremap on regular memory to get an uncached mapping, which causes problems on ARMv6 and higher due to aliasing with the cached linar kernel mapping. Make sure this gets fixed before the driver graduates from staging.

| | | | | | | | | | | | | | | | | | The services_init() and services_exit() functions don't do anything, so they are removed, and as these are the only two functions defined in services.c and services.h, then these files are also removed.

| * staging: tidspbridge: Remove cfg.c and cfg.h filesIvan Gomez Castellanos2010-08-3122-138/+7Star
| | | | | | | | | | | | | | | | So far, the cfg.c file is empty, and the function prototypes in cfg.h are not used in any place. So they can be removed. Signed-off-by: Ivan Gomez Castellanos <ivan.gomez@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | | | | | | | | | As the services directory is going to be removed, the cfg_set_object function has also to be removed. Since the driver object handle is retrieved from the drv_data structure, then the word "Registry" is replaced by "driver data" in the comments. Signed-off-by: Ivan Gomez Castellanos <ivan.gomez@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
| * staging: tidspbridge: Remove cfg_set_dev_object()Ivan Gomez Castellanos2010-08-313-61/+16Star

| | | | | | | | | | | | | | | | | | | | | | | | | | | | As the services directory is going to be removed, the cfg_get_object function has also to be removed. Since the driver object handle is retrieved from the drv_data structure, then the word "Registry" is replaced by "driver data" in the comments. Also, the hdrv_obj is not used in function omap34_xx_bridge_remove(), so it is removed. Signed-off-by: Ivan Gomez Castellanos <ivan.gomez@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | As the services directory is going to be removed, the cfg_get_exec_file function has also to be removed. This patch also avoids a possible NULL pointer dereference in function cfg_get_exec_file(), when drv_datap is checked for NULL and then pass drv_datap->base_img as argument to strlen().

| * staging: tidspbridge: Remove cfg_get_dev_object() and do a trivial cleanupIvan Gomez Castellanos2010-08-313-68/+24Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The cfg_get_dev_object function is only used in one place and because of its simplicity, it can be removed. The parameter *value can be left uninitialized if the strcmp() returns a nonzero value, so in the function dev_remove_device(), the hdev_obj could be used uninitialized and could be dereferenced in dev_destroy_device(). This patch fixes this issue, and also removes the dev_obj pointer which is not used. Signed-off-by: Ivan Gomez Castellanos <ivan.gomez@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * staging: tidspbridge: Remove cfg_get_auto_start()Ivan Gomez Castellanos2010-08-313-49/+6Star
| | | | | | | | | | | | | | | | | | | | | | As the services directory is going to be removed, this patch is needed. The function cfg_get_auto_start() only assigns a value to the flag tmp, and it is only called by the function api_init_complete2(). So the function cfg_get_auto_start() is not required.

| | | | | | | | | | | | | | | | | | | | | | As the services directory is going to be removed, this patch is needed. ntfy.c only contained the function dsp_notifier_event(), and since this function calls sync_set_event(), then the dsp_notifier_event() is moved to the sync.c file.
