From e90e236250e9edd2584a3405d0b2482ef687a637 Mon Sep 17 00:00:00 2001 From: ianyar Date: Thu, 14 Nov 2019 15:39:03 +0530 Subject: scsi: pm80xx: Increase timeout for pm80xx mpi_uninit_check The function mpi_uninit_check takes longer for inbound doorbell register to be cleared. Increased the timeout substantially so that the driver does not fail to load.
