Subject: [PATCH-for-5.0 10/12] hw/misc/macio/macio: Add missing error-propagation code
Date: Wed, 25 Mar 2020 20:18:28 +0100
Message-ID: <20200325191830.16553-11-f4bug@amsat.org> (raw)
In-Reply-To: <20200325191830.16553-1-f4bug@amsat.org>

Running the coccinelle script produced:

  $ spatch \
    --macro-file scripts/cocci-macro-file.h --include-headers \
    --sp-file scripts/coccinelle/object_property_missing_error_propagate.cocci \
    --keep-comments --smpl-spacing --dir hw

  [[manual check required: error_propagate() might be missing in object_property_set_bool() hw/misc/macio/macio.c:350:8]]

Add the missing error_propagate() after manual review.
