From: James Bottomley Date: Wed, 9 May 2007 09:33:29 +0000 (-0700) Subject: mca: fix bus matching X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=809aa5048fb7e7fd3bf0aa1fb169c42db0f63b08;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git mca: fix bus matching There's a bug in the MCA bus matching algorithm in that it promotes from signed short to int before comparing with the actual id and does sign extension on anything > 0x7fff (which means that pos ids > 0x7fff never get correctly matched).
