Since the Armbian sources refer to linux 4.19.76 as being linux-mainline, all the patches from linux-4.19 were moved to linux-mainline_4.19 and the linux_4.19.76 recipes was named accordingly. This patch makes 4.19.76 as default version for linux Signed-off-by: Vicentiu Galanopulo <vicentiu@balena.io>
