New patch attempt attached. Some comments though.

For me, initializing a variable in declaration or not, or placing a 
comment or not, is coding style... but let's not argue about that.

I don't agree with two of your comments.

First, initializing a struct with {0} instead of using a memset(). I 
always use memset() because gcc gives a warning of "missing 
initializer" in the other way if you activate the '-Wextra' option.

Second, testing ioctl error against -1 instead of negative. As rule of 
thumb I test for a function error as the negation of returning OK. Most 
ioctls return 0 for OK, but some return a positive value, hence testing 
for negative.
