Subject: [PATCH 02/16] macfb: fix black and white modes
Date: Mon, 24 Oct 2011 01:11:10 +1100 [thread overview]
Message-ID: <20111023141119.848736612@telegraphics.com.au> (raw)
In-Reply-To: 20111023141108.856998818@telegraphics.com.au
[-- Attachment #1: macfb-bw-fix --]
[-- Type: text/plain, Size: 5966 bytes --]
macfb won't init in black & white modes since fb_alloc_cmap() no longer works for zero cmap length. Fix this and also clean up a few printk's and some stylistic inconsistencies.
