The patch enters next with the merge of

	git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine.git next

Ah, the patch that became cccc46ae3623 (i.e. patch #14) is part of a
bigger series. Its patch #1 removes s3c24xx.c (which you pointed out to be still
broken) and patch #2 includes the change I suggested here.

+1

BTW, cccc46ae3623 is included in next since next-20221107 and breaks
(at least) arm/s3c2410_defconfig. So I would consider reverting
cccc46ae3623 a fix. (Added linux-next to Cc:)

Best regards
Uwe
