From a7afeb31421bd6810c903468b23734baa6999438 Mon Sep 17 00:00:00 2001 From: Adrian Schmutzler Date: Mon, 19 Oct 2020 15:30:44 +0200 Subject: ipq40xx: remove support for kernel 4.19 The target uses 5.4 as default kernel since 03/2020. Kernel 4.19 support is not really maintained anymore, it does not seem to be needed, and removing it will make upcoming driver updates easier. Thus, remove it.

descriptor -field and use the info to allocate in the subsequent iteration. - -Change-Id: Ie4fd3b6cf25304e5db2c9247a498791e7e9bb4aa -Signed-off-by: Rakesh Nair -Signed-off-by: Kan Yan -Reviewed-on:
