V5: - Removed mhi_uci_drv structure. - Used idr instead of creating global list of uci devices. - Used kref instead of local ref counting for uci device and open count. - Removed unlikely macro.
V4: - Fix locking to protect proper struct members. - Updated documentation describing uci client driver use cases. - Fixed uci ref counting in mhi_uci_open for error case. - Addressed style related review comments.
V3: Added documentation for MHI UCI driver.
V2: Added mutex lock to prevent multiple readers to access same mhi buffer which can result into use after free.
