X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=14d7f3efe923bc60839c65f9818793c64b4d708b;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ext4: remove unused local variable

In get_implied_cluster_alloc(), rr_cluster_end was being
defined and set, but was never used.  Removed this.
