[PATCH 2/6] drm/fb: Fix depth 15 support in drm_fb_helper.c

fbset can pass var->bits_per_pixel = 15 when doing fbset -depth 15, so we need to "correct" that to bpp 16 / depth 15. Additionally, we make it possible to pass 15 as an argument to drm_fb_helper_single_fb_probe() which will similarily select a bpp of 15 and a depth of 15. Signed-off-by:
