Here are 3 patches against the 'modules-next' branch of Jessica Yu's 'linux.git' repo.
I'm doing some refactoring in module_sig_check()...
[1/3] module: merge repetitive strings in module_sig_check()
[2/3] module: avoid *goto*s in module_sig_check()
[3/3] module: only handle errors with the *switch* statement in module_sig_check()
