Quote from: Ilh on July 14, 2014, 08:42:45 AMHello,This may sound as a newbie request, but can somebody tell me how to update the existing SPI driver module -> I want for example to put some debug messages to see what happens down there. Driver is installed with Kernel compilation by selecting SPI enable and SPI for user mode enable in the menuconfig. Will rmmod and insmod work?
printk(KERN_WARNING ": some message\n");
