Otherwise, this info will not be added when errp == &error_fatal (the program will exit prior to the error_append_hint() or error_prepend() call). Fix such cases. If we want to check error after errp-function call, we need to introduce local_err and then propagate it to errp. Instead, use ERRP_AUTO_PROPAGATE macro, benefits are: 1. No need of explicit error_propagate call 2. No need of explicit local_err variable: use errp directly 3. ERRP_AUTO_PROPAGATE leaves errp as is if it's not NULL or &error_fatal, this means that we don't break error_abort (we'll abort on error_set, not on error_propagate) This commit is generated by command sed -n '/^Parallel NOR Flash devices$/,/^$/{s/^F: //p}' \ MAINTAINERS | \ xargs git ls-files | grep '\.[hc]$' | \ xargs spatch \ --sp-file scripts/coccinelle/auto-propagated-errp.cocci \ --macro-file scripts/cocci-macro-file.h \ --in-place --no-show-diff --max-width 80 Reported-by: Kevin Wolf Reported-by: Greg Kurz Signed-off-by: Vladimir Sementsov-Ogievskiy Reviewed-by: Philippe Mathieu-Daudé [Commit message tweaked] Signed-off-by: Markus Armbruster --- hw/block/pflash_cfi01.c | 7 +++---- hw/block/pflash_cfi02.c | 7 +++---- 2 files changed, 6 insertions(+), 8 deletions(-) diff --git a/hw/block/pflash_cfi01.c b/hw/block/pflash_cfi01.c index cddc3a5a0c..859cfeae14 100644 --- a/hw/block/pflash_cfi01.c +++ b/hw/block/pflash_cfi01.c @@ -696,12 +696,12 @@ static const MemoryRegionOps pflash_cfi01_ops = { static void pflash_cfi01_realize(DeviceState *dev, Error **errp) { + ERRP_AUTO_PROPAGATE(); PFlashCFI01 *pfl = PFLASH_CFI01(dev); uint64_t total_len; int ret; uint64_t blocks_per_device, sector_len_per_device, device_len; int num_devices; - Error *local_err = NULL; if (pfl->sector_len == 0) { error_setg(errp, "attribute \"sector-length\" not specified or zero."); @@ -735,9 +735,8 @@ static void pflash_cfi01_realize(DeviceState *dev, Error **errp) &pfl->mem, OBJECT(dev), &pflash_cfi01_ops, pfl, - pfl->name, total_len, &local_err); - if (local_err) { - error_propagate(errp, local_err); + pfl->name, total_len, errp); + if (*errp) { return; } diff --git a/hw/block/pflash_cfi02.c b/hw/block/pflash_cfi02.c index b40ce2335a..15035ee5ef 100644 --- a/hw/block/pflash_cfi02.c +++ b/hw/block/pflash_cfi02.c @@ -724,9 +724,9 @@ static const MemoryRegionOps pflash_cfi02_ops = { static void pflash_cfi02_realize(DeviceState *dev, Error **errp) { + ERRP_AUTO_PROPAGATE(); PFlashCFI02 *pfl = PFLASH_CFI02(dev); int ret; - Error *local_err = NULL; if (pfl->uniform_sector_len == 0 && pfl->sector_len[0] == 0) { error_setg(errp, "attribute \"sector-length\" not specified or zero."); @@ -792,9 +792,8 @@ static void pflash_cfi02_realize(DeviceState *dev, Error **errp) memory_region_init_rom_device(&pfl->orig_mem, OBJECT(pfl), &pflash_cfi02_ops, pfl, pfl->name, - pfl->chip_len, &local_err); - if (local_err) { - error_propagate(errp, local_err); + pfl->chip_len, errp); + if (*errp) { return; }
