Subject: [PATCH] SCSI: FlashPoint: rename si_flags field
Date: Sat, 29 May 2021 16:48:57 -0700
Message-ID: <20210529234857.6870-1-rdunlap@infradead.org> (raw)

The BusLogic driver has build errors on ia64 due to a name collision
(in the #included FlashPoint.c file).
Rename the struct field in struct sccb_mgr_info from si_flags to
si_mflags (manager flags) to mend the build.

This is the first problem. There are 50+ others after this one:
