docs: driver-api: remove a duplicated index entry
The ipmb file was added twice at index.rst. That sounds to be because the same patch was applied twice, via different git trees: commit f6ae22d64433fd8e08654adad7966299da931bb9 Author: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> Commit: Jonathan Corbet <corbet@lwn.net> docs: ipmb: place it at driver-api and convert to ReST commit ac499fba98c3c65078fd84fa0a62cd6f6d5837ed Author: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> Commit: Corey Minyard <cminyard@mvista.com> docs: ipmb: place it at driver-api and convert to ReST With Sphinx 4.0.0 development tree, a new warning is produced due to that: .../Documentation/driver-api/index.rst:14: WARNING: duplicated entry found in toctree: driver-api/ipmb The fix is trivial: just drop the duplicated line. Fixes: f6ae22d64433 ("docs: ipmb: place it at driver-api and convert to ReST") Fixes: ac499fba98c3 ("docs: ipmb: place it at driver-api and convert to ReST") Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/623fb26a8409a7b002e45bdbb6f517ac08fd508a.1602753121.git.mchehab+huawei@kernel.org Signed-off-by: Jonathan Corbet <corbet@lwn.net>
