From 33ddc16f1003fc13d57ebe5061b29e16e6f84848 Mon Sep 17 00:00:00 2001 From: Brian Johnson Date: Sun, 18 Apr 2010 21:42:40 -0300 Subject: V4L/DVB: gspca - sn9c20x: HAS_BUTTON flag -> HAS_NO_BUTTON flag Reverse HAS_BUTTON logic since most webcams either have a button or if they don't don't bother to send any interrupts. However I have at least one model that appears to leave the button GPIO floating and can send a bogus interrupt.
