[PATCH v3 1/4] bus: mhi: core: Add helper API to return number of free TREs

Introduce mhi_get_no_free_descriptors() API to return number of TREs available to queue buffer. MHI clients can use this API to know before hand if ring is full without calling queue API. Signed-off-by: Hemant Kumar --- drivers/bus/mhi/core/main.c | 12 include/linux/mhi.h
