From: Russell King Date: Fri, 28 Oct 2005 13:56:04 +0000 (+0100) Subject: [ARM] 4/4 Combine oprofile common and init code X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c6b9dafce3e3b434a3e7ffd5072815c03d18cc84;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git [ARM] 4/4 Combine oprofile common and init code There is nothing special about having the init code separate from the common code, so combine the two.
