From 4451342db5b5b779add112c6b15d676f07c73b33 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Tue, 20 May 2008 06:24:04 -0300 Subject: V4L/DVB (7927): ivtv: simplify gpio initialization for XCeive tuners. Separate gpio_init field and xceive_pin and combine the two when the gpio is initialized. So there is no longer any need to set the xceive pin in the gpio_init values, simplifying the creation of a new card definition.
