ASoC: simple-card-utils: fix graph_util_is_ports0() for DT overlays

2026-03-25T10:05:46+00:00

[ Upstream commit 4185b95f8a42d92d68c49289b4644546b51e252b ] graph_util_is_ports0() identifies DPCM front-end (ports@0) vs back-end (ports@1) by calling of_get_child_by_name() to find the first "ports" child and comparing pointers. This relies on child iteration order matching DTS source order. When the DPCM topology comes from a DT overlay, __of_attach_node() inserts new children at the head of the sibling list, reversing the order. of_get_child_by_name() then returns ports@1 instead of ports@0, causing all front-end links to be classified as back-ends. The card registers with no PCM devices. Fix this by matching the unit address directly from the node name instead of relying on sibling order.

ASoC: simple-card-utils: use __free(device_node) for device node

[ Upstream commit 419d1918105e5d9926ab02f1f834bb416dc76f65 ] simple-card-utils handles many type of device_node, thus need to use of_node_put() in many place. Let's use __free(device_node) and avoid it.

ASoC: audio-graph-card2: Purge absent supplies for device tree nodes

2024-12-09T09:31:39+00:00

[ Upstream commit f8da001ae7af0abd9f6250c02c01a1121074ca60 ] The audio graph card doesn't mark its subnodes such as multi {}, dpcm {} and c2c {} as not requiring any suppliers. This causes a hang as Linux waits for these phantom suppliers to show up on boot. Make it clear these nodes have no suppliers.

ASoC: simple-card: fixup asoc_simple_probe() error handling

2023-09-19T12:48:38+00:00

asoc_simple_probe() is used for both "DT probe" (A) and "platform probe" (B). It uses "goto err" when error case, but it is not needed for "platform probe" case (B). Thus it is using "return" directly there. static int asoc_simple_probe(...) { ^ if (...) { | ... (A) if (ret < 0) | goto err; v } else { ^ ... | if (ret < 0) (B) return -Exxx; v } ... ^ if (ret < 0) (C) goto err; v ... err: (D) simple_util_clean_reference(card); return ret; } Both case are using (C) part, and it calls (D) when err case. But (D) will do nothing for (B) case. Because of these behavior, current code itself is not wrong, but is confusable, and more, static analyzing tool will warning on (B) part (should use goto err). To avoid static analyzing tool warning, this patch uses "goto err" on (B) part.
