From: Sean Anderson Date: Mon, 26 Jul 2021 16:36:53 +0000 (-0400) Subject: mmc: sdio: Print contents of unknown CIS tuples X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e285b3e064647c6b4b822ade9acb0f3ffd6b1317;p=linux.git mmc: sdio: Print contents of unknown CIS tuples Print out the contents of the offending tuples when we do print them. This can make it easier to debug, since these tuples are not exposed to userspace anywhere else. We are limited to 64 bytes, so keep printing out the full length in case the tuple is truncated.
