From: Jes Sorensen Date: Mon, 29 Feb 2016 22:05:20 +0000 (-0500) Subject: rtl8xxxu: Use size of source pointer when copying efuse data X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3e84f9386162878deb146a7e4f05710693f1a9c7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git rtl8xxxu: Use size of source pointer when copying efuse data Some newer chips have more channel groups in their efuse parameter tables, so use the size of the source, rather than the destination when copying them out. This avoids copying garbage when increasing the common array sizes.
