From 118bfd76c9c604588cb3f97811710576f58e5a76 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 7 Jul 2020 18:05:32 +0200 Subject: qdev: Use returned bool to check for qdev_realize() etc. failure Convert foo(..., &err); if (err) { ... } to if (!foo(..., &err)) { ... } for qdev_realize(), qdev_realize_and_unref(), qbus_realize() and their wrappers isa_realize_and_unref(), pci_realize_and_unref(), sysbus_realize(), sysbus_realize_and_unref(), usb_realize_and_unref(). Coccinelle script: @@ identifier fun = { isa_realize_and_unref, pci_realize_and_unref, qbus_realize, qdev_realize, qdev_realize_and_unref, sysbus_realize, sysbus_realize_and_unref, usb_realize_and_unref }; expression list args, args2; typedef Error; Error *err; @@ - fun(args, &err, args2); - if (err) + if (!fun(args, &err, args2)) { ... } Chokes on hw/arm/musicpal.c's lcd_refresh() with the unhelpful error message "no position information". Nothing to convert there; skipped. Fails to convert hw/arm/armsse.c, because Coccinelle gets confused by ARMSSE being used both as typedef and function-like macro there. Converted manually. A few line breaks tidied up manually.
