[PATCH] fpga: bridge: fix kernel-doc

[Marco Pagani]

Fix the following warnings issued by the kernel-doc script:

drivers/fpga/fpga-bridge.c:99: warning: No description found for return value of 'of_fpga_bridge_get'
drivers/fpga/fpga-bridge.c:163: warning: No description found for return value of 'fpga_bridges_enable'
drivers/fpga/fpga-bridge.c:187: warning: No description found for return value of 'fpga_bridges_disable'
drivers/fpga/fpga-bridge.c:238: warning: No description found for return value of 'of_fpga_bridge_get_to_list'
drivers/fpga/fpga-bridge.c:268: warning: No description found for return value of 'fpga_bridge_get_to_list'

The patch is based on top of 38dbcd697770 ("fpga: bridge: fix kernel-doc parameter description").

I see you are trying to clean up the warnings, but I found more in
drivers/fpga. Could you help at least fix all core code,
(of-)fpga-bridge/region/mgr.c/h in series? Thanks.

I didn't found this commit, could you elaborate? And you could put this
info in changelog, don't show it up in mainline.

Thanks,

Sorry, I accidentally put the wrong hash. I was referring to this patch:

https://lore.kernel.org/linux-fpga/20230301140309.512578-1-marpagan@redhat.com/

That has been applied to char-misc-next:

https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git/commit/drivers/fpga/fpga-bridge.c?h=char-misc-next&id=7ef1a2c1c9dffa177ecc3ea50b7f5ee63a621137
