BTW, it's fortunate that you are maintaing it. The I2C code in cirrusfb uses vga_wseq() and vga_rseq(). Is it safe WRT races between I2C adapter code and fb code? I don't see any locking here, and both functions are non-atomic (write merging and posting will not break it, but it looks like I need a lock for concurent access). -- Krzysztof Halasa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
