From e81bdae440fa7cc7dcbfb4f0fcfafb1f4350bc31 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20L=C3=B6hle?= Date: Sun, 27 Nov 2022 17:46:31 +0000 Subject: [PATCH] mmc: core: Remove non-data R1B ioctl workaround The workaround of pretending R1B non-data transfers are data transfers in order for the busy timeout to be respected by the host controller driver is removed. It wasn't useful in a long time. Initially the workaround ensured that R1B commands did not time out by setting the data timeout to be the command timeout in commit cb87ea28ed9e ("mmc: core: Add mmc CMD+ACMD passthrough ioctl"). This was moved inside an if-clause with idata->buf_bytes being set in commit 4d6144de8ba2 ("mmc: core: check for zero length ioctl data"). Since the workaround is now inside the idata->buf_bytes clause and intended to fix R1B non-data transfers, that do not have buf_bytes set, we can remove the workaround altogether. This was dead code, since data transfers doesn't use R1B commands.
