[PATCH 1/1] platform/chrome: chromeos_pstore: set user space log size

From: Sarthak Kukreti
Date: Wed Apr 01 2020 - 20:16:46 EST


On x86 ChromiumOS devices, the pmsg_size is set to 0 (check
/sys/module/ramoops/parameters/pmsg_size): this prevents use of
pstore-pmsg, even if CONFIG_PSTORE_PMSG is enabled. Set pmsg_size
to a value that is consistent with the size used on non-x86 ChromiumOS
devices.
