Subject: s390/cpu_mf: remove register variable in __ecctr()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=26f268ac682854345531325c7c0d803b8c573228;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

s390/cpu_mf: remove register variable in __ecctr()

compiler decide the register to be used.
