sdhci: Timeout waiting for Buffer Read Ready interrupt during tuning procedure

Hi,
I think I have a similar problem as described in this thread:
https://up-community.org/forum/public-upboardhw/1170-emmc-error-kernel-remounting-filesystem-to-read-only
I just got new UP board with 4 G RAM / 32 G eMMC and installed latest CentOS 7 with updated kernel 3.10.0-514.26.2.el7.x86_64. It has been running without a problem for a couple of days acting as an asterisk/FreePBX box. Today I started observing (3 times as of now) the following kernel warning:
[ 9854.847519] sdhci: Timeout waiting for Buffer Read Ready interrupt during tuning procedure, falling back to fixed sampling clock
[ 9864.869413] mmc0: Timeout waiting for hardware interrupt.

The filesystem does not get remounted as readonly as in abovementioned thread (perhaps because the default filesystem for CentOS is XFS) but the warning indicates that it might be a problem that this patch has been designed for:
http://www.spinics.net/lists/linux-mmc/msg40826.html
I have a couple of questions:
- What is your opinion? Will this patch solve the problem? (I'm planing to build my own patched CentOS kernel)
- Is it possible for filesystem to get corrupted because of this problem/warning occuring?
- Do you plan to submit those patches upstream so that other distributions would run on UP board without problems?
Thanks,

I'm happy to inform that the abovementioned patch helped solve the problem. With just that patch applied to latest CentOS 7 kernel, I built the kernel and am now running it on the UP board. Since than I saw the following in the kernel messages:
[ 8842.316198] sdhci: Timeout waiting for Buffer Read Ready interrupt during tuning procedure, falling back to fixed sampling clock
...but there were no I/O errors as a consequence. Building CentOS 7 kernel was easy following these instructions:
https://wiki.centos.org/HowTos/Custom_Kernel
I didn't build it on UP board - it would take too long. I created a virtual machine on my fast i7 workstation with minimal CentOS installation (1 minute) and just followed further instructions from CentOS wiki...
