Subject: [PATCH v2 2/7] fpga-mgr: make write_complete() op optional
Date: Tue,  8 Jun 2021 12:55:01 -0700	[thread overview]
Message-ID: <20210608195506.3022550-4-trix@redhat.com> (raw)
In-Reply-To: <20210608195506.3022550-1-trix@redhat.com>

From: Tom Rix <trix@redhat.com>

An FPGA manager should not be required to provide a
write_complete function if there is nothing.  Move
the op check to the existing wrapper.
Default to success.
Remove noop function.
