From 986ce4510b37ba684aaebd3eb0e6ee0c03906ed8 Mon Sep 17 00:00:00 2001 From: Pete Eberlein <pete@sensoray.com> Date: Wed, 13 Jan 2010 19:15:48 -0300 Subject: [PATCH] V4L/DVB: s2250: Fix write_reg i2c address The kernel i2c model uses right-aligned 7-bit i2c addresses, but the 2250 firmware uses an 8-bit address in the usb vendor request. A previous patch by Jean Delvare shifted the i2c addresses 1 bit to the right, and this patch fixes the write_reg function to shift it back before sending the vendor request.
