Trivial logging comments:

One of the printks is not prefaced and the printks
and dev_printks are not consistently using either
periods or no periods.

Some possible substitutions:

s/dev_printk(KERN_INFO/dev_info(/
s/dev_printk(KERN_DEBUG/dev_dbg(/
s/printk(KERN_INFO/pr_info(/

I think it would be better to use:
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
and remove the "%s: " ... KBUILD_MODNAME

Perhaps
	pr_info("Found a '%s'\n", id->ident);

pr_debug?

I think this will look odd when printed.
There's a tab on the second line, not on third.
Perhaps:
		pr_info("Skipping hardware detection.\n");
		pr_info("Please send 'dmidecode' output to dave@...1.net\n");

	pr_info("No LED devices found\n");
	pr_info("Registering PCI driver\n");
	pr_info("Unregistering PCI driver\n");
