Subject: serial: bfin_sport_uart: Use resource size to fix off-by-one error
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e114474cf5c7fe7ab94dd4f5938ffa51c9af77c4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

serial: bfin_sport_uart: Use resource size to fix off-by-one error

Use the resource_size function instead of manually calculating the
resource size. This actually fixes an off-by-one error.
