fpga: mgr: kernel-doc fixes
Clean up the kernel-doc documentation in fpga-mgr.c and fix the following warnings when documentation is built: ./drivers/fpga/fpga-mgr.c:252: warning: Function parameter or member 'info' not described in 'fpga_mgr_buf_load' ./drivers/fpga/fpga-mgr.c:252: warning: Excess function parameter 'flags' description in 'fpga_mgr_buf_load' Signed-off-by: Alan Tull <atull@kernel.org> Acked-by: Moritz Fischer <mdf@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
