+Oh, and if you did *not*, please give this patch a try.
+I've been meaning to test it.

+Sometimes it's awkward to make sure that the array in the
+platform_data handed to the leds-gpio driver has only valid
+data ... some leds may not be always available, and coping
+with that currently requires patching or rebuilding the array.
+
+This patch fixes that by making it be OK to pass an invalid
+GPIO (such as "-EINVAL") ... such table entries are skipped.

+Subject: [ARM] fix section-based ioremap
+X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fkhilman%2Flinux-omap-pm.git;a=commitdiff_plain;h=9ae635f00a568cf95dbd15fa2c50eaee0aa27d2a
+
+[ARM] fix section-based ioremap
+
+Tomi Valkeinen reports:
+  Running with latest linux-omap kernel on OMAP3 SDP board, I have
+  problem with iounmap(). It looks like iounmap() does not properly
+  free large areas. Below is a test which fails for me in 6-7 loops.
+
+	for (i = 0; i < 200; ++i) {
+		vaddr = ioremap(paddr, size);
+		if (!vaddr) {
+			printk("couldn't ioremap\n");
+			break;
+		}
+		iounmap(vaddr);
+	}
+
+The changes to vmalloc.c weren't reflected in the ARM ioremap
+implementation.  Turns out the fix is rather simple.

++OMAP2/3 Display Subsystem
++-------------------------
++
++This is an almost total rewrite of the OMAP FB driver in drivers/video/omap
++(let's call it DSS1). The main differences between DSS1 and DSS2 are DSI,
++TV-out and multiple display support.
++
++The DSS2 driver (omap-dss module) is in arch/arm/plat-omap/dss/, and the FB,
++panel and controller drivers are in d
