X-Git-Tag: v2.6.32-rc1~645^2~8 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0e3eaadfe3da84f98250ad8a2c36e87fe00e42ee;p=pandora-kernel.git ARM: OMAP4: Fix NULL pointer dereference crash. After the patch series "[PATCH 00/14] OMAP PM fixes for .31-rc" merge in 2.6.31-rc5, the kernel crashed during boot on OMAP4430. This patch fixes it by adding UART4 support and related code. Without this patch omap_serial_init() would produce " NULL pointer dereference" and kernel crashes in the bootup on OMAP4430 platform. Some more info on the merge issue can be found here.
