Subject: credit2: avoid to shadow the variable "cur" in runq_tickle
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~2332
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=568ff32927ecc68765973ad5b590b48e045dee4a;p=xen.git

credit2: avoid to shadow the variable "cur" in runq_tickle

The variable "cur" is declared twice within "cur". However the top
declaration could be re-used avoiding re-declaring another time the
variable.
