Subject: regulatory: remove redundant isalpha() check
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d4f2c8819a51f31ef0f929574ce8d80b323c6a76;p=linux-beck.git

regulatory: remove redundant isalpha() check

toupper() only modifies lower-case letters, so
the isalpha() check is redundant; remove it.
