Subject: [MMC] Change SDHCI version error to a warning
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8b1b21853bab15fe5b60b8222786fe036c4dc365;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[MMC] Change SDHCI version error to a warning

O2 Micro's controllers have a larger specification version value and are
therefore denied by the driver. When bypassing this check they seem to work
fine. This patch makes the code a bit more forgiving by changing the error
to a warning.
