Subject[PATCH 1/2] module: merge repetitive strings in module_sig_check()
From
Date
The 'reason' variable in module_sig_check() points to 3 strings across
the *switch* statement, all needlessly starting with the same text. Let's
put as much of the starting text as we can into the pr_notice() call (this
includes some rewording of the 1st message) -- it saves 37 bytes of object
code (x86 gcc 10.2.1).
