[PATCH V3 5/9] phy: qcom-qmp-ufs: Remove qmp_ufs_com_init()

Nitin Rawat
2025-04-10T09:01:36Z

Simplify the qcom ufs phy driver by inlining qmp_ufs_com_init() into
qmp_ufs_power_on(). This change removes unnecessary function calls and
ensures that the initialization logic is directly within the power-on
routine, maintaining the same functionality.
