Subject: [PATCH] scsi: pm8001: clean up structurally dead code when PM8001_USE_MSIX is defined
Date: Thu, 28 Mar 2019 23:43:28 +0000 [thread overview]
Message-ID: <20190328234328.15860-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
When macro PM8001_USE_MSIX is defined there are redundant dead code
calls to pm8001_chip_intx_interrupt_{enable|disable}. Clean this up
by compiling in the appropriate enable/disable handlers for the
defined PM8001_USE_MSIX and undefined PM8001_USE_MSIX cases.
