Subject: fix more workqueue build breakage (tps65010)
From: David Brownell <david-b@xxxxxxxxxxx>
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.
