From 34fcdcd7c2fb81fddd14292193ef2a42ba958a3a Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sun, 23 Feb 2020 16:46:01 +0100 Subject: [PATCH] kernel: Remove nvmem hack patch from 5.4 The nvmem framework is now used in net/ethernet/eth.c and the nvmem sysfs is split into a separate Kconfig option. More work would be needed to adapt this patch for the broader use. The current patch compiles fine on ath79, but it breaks the x86 target. nvmem is also compiled into the kernel for most of our targets for example ath79 anyway, so patching the kernel to remove it is now harder and not the case on multiple targets anyway. Instead of making this work on kernel 5.4 just remove this hack patch.
