| |
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@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' [-Werror=unused-variable]
This uses the same #ifdef to hide the variable when the code using it is hidden.
