Why don't you ask on the i2c mailing list? Cc added. Personally I have no objection, but dependencies can be tricky so you'll have to be careful. video is early in the link order at the moment. > What do other frame buffer drivers handle the absence of i2c during early > boot? Interestingly enough, they appear to do fine, despite the linking order. Maybe because i2c_init is a subsys_initcall() while framebuffer drivers are initialized with module_init()? Then I'm not sure why your own driver has a problem there. -- Jean Delvare _______________________________________________ i2c mailing list [email protected] http://lists.lm-sensors.org/mailman/listinfo/i2c
