4.4-stable review patch.  If anyone has any objections, please let me know.


From: Arnd Bergmann <a...@arndb.de>

commit b97baa3e22e18dac42001e665cf27ad1211bf878 upstream.

The i2c client pointer is only used when CONFIG_I2C is set, and
otherwise produces a compile-time warning:

drivers/media/usb/hdpvr/hdpvr-core.c: In function 'hdpvr_probe':
drivers/media/usb/hdpvr/hdpvr-core.c:276:21: error: unused variable 'client' 

This uses the same #ifdef to hide the variable when the code using
it is hidden.
