Subject: rtlwifi: rtl8821ae: Make sure loop counter is signed on all architectures
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=005a425b24e101d312eca669b96a6b71d75e97fc;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

rtlwifi: rtl8821ae: Make sure loop counter is signed on all architectures

The for-loop condition does not work correctly on architectures where
"char" is unsigned. Fix it by using an "int", which may also result in
more efficient code.
