Date: Mon, 19 Nov 2007 22:33:02 +0100 From: Stanislav Brabec <utx@...guin.cz> To: kernel list <linux-kernel@...r.kernel.org> Cc: linux-mtd@...ts.infradead.org, Pavel Machek <pavel@....cz> Subject: [PATCH] fix CONFIG_MTD_SHARP_SL if CONFIG_MTD=m (try2) Sharp Zaurus SL-C3200 with CONFIG_MTD=m and CONFIG_MTD_SHARP_SL=y (as it is bool) lost support for the ROM flash. With CONFIG_MTD=y it has no problems. It is caused by losing of compiled code of drivers/mtd/maps/sharpsl-flash.o. It was linked to drivers/mtd/maps/built-in.o and drivers/mtd/built-in.o, but lost and not linked to drivers/built-in.o (because CONFIG_MTD!=y). Patch below fixes this problem by creating sharpsl-flash.ko (and the code works correctly as a module). This is second try (first sent Nov 10 to linux-mtd@...ts.infradead.org).
