Three versions within one day that's way too much. And b4 diff does not work:
b4 diff 20260629072055.896322-1-s-k6@ti.com Looking up https://lore.kernel.org/all/20260629072055.896322-1-s-k6@ti.com/ Grabbing thread from lore.kernel.org/all/20260629072055.896322-1-s-k6@ti.com/t.mbox.gz Checking for older revisions Grabbing search results from lore.kernel.org Added from v1: 6 patches --- Analyzing 14 messages in the thread WARNING: duplicate messages found at index 2 Subject 1: memory: ti-k3-fsas: Add TI FSS_FSAS driver Subject 2: memory: ti-k3-fsas: Add TI FSS_FSAS driver 2 is not a reply... assume additional patch WARNING: duplicate messages found at index 1 Subject 1: dt-bindings: memory: Add TI FSS_FSAS binding Subject 2: dt-bindings: memory: Add TI FSS_FSAS binding 2 is not a reply... assume additional patch Preparing fake-am for v1: dt-bindings: memory: Add TI FSS_FSAS binding ERROR: v1 series incomplete; unable to create a fake-am range
If you want to make it difficult for maintainer to review, your patches will be moved to the end of the queue.
