Sure.

Hmm... I didn't understand what you're wanting with this change. Before this patch,
there are:

v4l@pedra ~/v4l/patchwork $ git grep config_vpif_params
drivers/media/platform/davinci/vpif.c:/* config_vpif_params
drivers/media/platform/davinci/vpif.c:static void config_vpif_params(struct vpif_params *vpifparams,
drivers/media/platform/davinci/vpif.c:    config_vpif_params(vpifparams, channel_id, found);
v4l@pedra ~/v4l/patchwork $ git grep vpif_config_params
drivers/media/platform/davinci/vpif_capture.c:static struct vpif_config_params config_params = {
drivers/media/platform/davinci/vpif_capture.h:struct vpif_config_params {
drivers/media/platform/davinci/vpif_display.c:static struct vpif_config_params config_params = {
drivers/media/platform/davinci/vpif_display.h:struct vpif_config_params {

After that, there are:

v4l@pedra ~/v4l/patchwork $ git grep vpif_config_params
drivers/media/platform/davinci/vpif.c:/* vpif_config_params
drivers/media/platform/davinci/vpif.c:static void vpif_config_params(struct vpif_params *vpifparams,
drivers/media/platform/davinci/vpif.c:    vpif_config_params(vpifparams, channel_id, found);
v4l@pedra ~/v4l/patchwork $ git grep config_vpif_params
drivers/media/platform/davinci/vpif_capture.c:static struct config_vpif_params config_params = {
drivers/media/platform/davinci/vpif_capture.h:struct config_vpif_params {
drivers/media/platform/davinci/vpif_display.c:static struct config_vpif_params config_params = {
drivers/media/platform/davinci/vpif_display.h:struct config_vpif_params {

So, I can't really see any improvement on avoiding duplicate names.

IMHO, the better would be to name those functions as:

vpif:		vpif_config_params (or, even better, vpif_core_config_params)
vpif_capture:	vpif_capture_config_params
vpif_display:	vpif_display_config_params

This way, duplication will be avoided and will avoid the confusing inversion between
vpif and config.

Mauro
