X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3c86c07baaa22e1ebae1922b5285f79a39e93d83;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

USB: ohci-s3c2410: use resource_size()

This patch uses the resource_size help function instead of
manually calculating the resource size. It can reduce the chance
of introducing off-by-one errors.
