[PATCH AUTOSEL 4.19 121/209] Input: silead - try firmware reload after unsuccessful resume

[Sasha Levin]

From: Julian Sax <jsbc@gmx.de>

[ Upstream commit dde27443211062e841806feaf690674b7c3a599f ]

A certain silead controller (Chip ID: 0x56810000) loses its firmware
after suspend, causing the resume to fail. This patch tries to load
the firmware, should a resume error occur and retries the resuming.
