I don't want to be nit-picking, but since we're talking about style...
for me these "} else {" statements are harder to parse than having them
on two lines this way :

         }
         else {

That's especially more true with "else if" as below :

		} else if (*esc >= 'A' && *esc <= 'Z') {
			value |= (*esc - 'A' + 10) << shift;
		} else if (*esc >= 'a' && *esc <= 'z') {
			value |= (*esc - 'a' + 10) << shift;
		} else {

I believe that most of the kernel code prefers the two-line format resluting
in this instead :

		}
		else if (*esc >= 'A' && *esc <= 'Z') {
			value |= (*esc - 'A' + 10) << shift;
		}
		else if (*esc >= 'a' && *esc <= 'z') {
			value |= (*esc - 'a' + 10) << shift;
		}
		else {

It's just a matter of taste I know, but for me they read easier, probably
because the braces do not affect alignment and the lines appear exactly
similar with or without the braces.

Thanks,
Willy
