Subject: [PATCH 1/1] scsi: ufs-qcom: remove broken hci version quirk

From: Subhash Jadavani <[email protected]>

UFSHCD_QUIRK_BROKEN_UFS_HCI_VERSION is only applicable for QCOM UFS host
controller version 2.x.y and this has been fixed from version 3.x.y
onwards, hence this change removes this quirk for version 3.x.y onwards.

This patch and all other ufs patches that you have posted recently,
do they all fall under one 'ufs-qcom fixes' patch series for fixes that
we would want to do?
If it is so, then please club them together in a series, so that
it's easy for reviewers and maintainers to review, and keep track
of all the patches that can get-in after the reviews.
If they belong to two or more separate patch-series then please
create such patch series.
It's difficult to read through a lot of [PATCH 1/1] ... patch.

Regards
Vivek
