Subject: dynamic debug: line queries failing due to uninitialized local variable
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bd8c154a62d47b0ec2abf87e35dccf081781d81c;p=linux-beck.git

dynamic debug: line queries failing due to uninitialized local variable

Settings of the form, 'line x module y +p', can fail arbitrarily due to an
uninitialized local variable. With this patch results are consistent, as
expected.
