From: David Brownell Date: Wed, 13 Dec 2006 08:33:46 +0000 (-0800) Subject: [PATCH] fix more workqueue build breakage (tps65010) X-Git-Tag: v2.6.20-rc1~134 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8c1bc04e793a7ff4004180aa42890c3d382ec87f;p=linux-2.6 [PATCH] fix more workqueue build breakage (tps65010) More fixes to build breakage from the work_struct changes ... this updates the tps65010 driver. Plus, fix some dependencies related to the way it's used on the OMAP OSK: force static linking there, since the resulting kernel can't link. NOTE that until the i2c core gets fixed to work without SMBUS_QUICK, kernels needing this driver must still use "tps65010.force=0,0x48" on the command line.
