X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a737222240848c771b2bc44880d3253fb7c03e13;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ACPICA: iASL: Enhance detection of non-ascii or corrupted input files. ACPICA commit 08170904011f1e8f817d9e3a9f2bb2438aeacf60 For the compiler part (not disassembler). - Characters not within a comment must be be ASCII (0-0x7F), and now either printable or a "space" character. Provides better detection of files that cannot be compiled. This patch only affects iASL which is not in the Linux upstream.
