From: Mauro Carvalho Chehab Date: Sat, 26 Apr 2008 17:05:58 +0000 (-0300) Subject: V4L/DVB (7753): saa7134: fix tuner setup X-Git-Tag: v2.6.26-rc1~352^2~25 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c117d05cd4c09342f97ba1c6ef63f0bae3239a39;p=linux-2.6 V4L/DVB (7753): saa7134: fix tuner setup Tuner setup were happening during i2c attach callback. This means that it would happen on two conditions: 1) if tuner module weren't load, it will happen at request_module("tuner"); 2) if tuner is not compiled as a module, or it is already loaded (for example, on setups with more than one tuner), it will happen when saa7134 registers I2C bus. Due to that, if tuner were loaded, tuner setup will happen _before_ reading the proper values at tuner eeprom. Since set_addr refuses to change for a tuner that were previously defined (except if the tuner_addr is set), this were making eeprom tuner detection useless. This patch removes tuner type setup from saa7134-i2c, moving it to the proper place, after taking eeprom into account.
