From: Tom Rix <trix@redhat.com> An FPGA manager is not required to provide a status() op. Add a wrapper consistent with the other op wrappers. Move the op check to the wrapper. Default to 0, no errors to report. Signed-off-by: Tom Rix <trix@redhat.com> --- drivers/fpga/fpga-mgr.c | 12 ++++++++---- 1 file changed, 8 insertions(+), 4 deletions(-)
