Subject: [PATCH] scsi: ufs: fix unmet dependency on RESET_CONTROLLER for RESET_TI_SYSCON

When RESET_TI_SYSCON is selected, and RESET_CONTROLLER
is not selected, Kbuild gives the following warning:

WARNING: unmet direct dependencies detected for RESET_TI_SYSCON
Depends on [n]: RESET_CONTROLLER [=n] && HAS_IOMEM [=y]
Selected by [y]:
- SCSI_UFS_MEDIATEK [=y] && SCSI_LOWLEVEL [=y] && SCSI [=y] && SCSI_UFSHCD_PLATFORM [=y] && ARCH_MEDIATEK [=y]

This is because RESET_TI_SYSCON is selected by
SCSI_UFS_MEDIATEK, but SCSI_UFS_MEDIATEK does
not select or depend on RESET_CONTROLLER, despite
RESET_TI_SYSCON depending on RESET_CONTROLLER.

These unmet dependency bugs were detected by Kismet,
a static analysis tool for Kconfig. Please advise if this
is not the appropriate solution.

Please keep the indentation consistent.

Hi Bart,

I have adjusted my text editor, and will resubmit the patch.
