From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnd Bergmann Date: Tue, 15 Jul 2014 08:39:57 +0000 Subject: PATCH] video: fix up versatile CLCD helper move Message-Id: <9561883.zqovrcBa4A@wuerfel> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-arm-kernel@lists.infradead.org commit 11c32d7b6274cb0f ("video: move Versatile CLCD helpers") moved files out of the plat-versatile directory but in the process got a few of the dependencies wrong: - If CONFIG_FB is not set, the file no longer gets built, resulting in a link error - If CONFIG_FB or CONFIG_FB_ARMCLCD are disabled, we also get a Kconfig warning for incorrect dependencies due to the symbol being 'select'ed from the platform Kconfig. - When the file is not built, we also get a link error for missing symbols. This patch should fix all three, by removing the 'select' statements, changing the Kconfig description of the symbol to be enabled in exactly the right configurations, and adding inline stub functions for the case when the framebuffer driver is disabled.
