This patch series serves to clean up the MHI host driver by removing an unnecessary counter and an unused function. It also renames a function to make it clearly worded. There is currently no user of this exported function which makes it is safe to do so now.
Bug fixes include adding a missing EXPORT_SYMBOL_GPL to a function, and adding a return value check to bail out of RDDM download in kernel panic path. An outlier among the group exports the mhi_get_exec_env() API for use by controller drivers, in case they need to determine behavior on the basis of the current execution environment. This set of patches was tested on arm64. v2: -Removed the declaration for mhi_get_exec_env() from internal.h -Improved on the error log message in RDDM download exit case due to unknown EE Bhaumik Bhatt (6): bus: mhi: core: Remove unnecessary counter from mhi_firmware_copy() bus: mhi: core: Add missing EXPORT_SYMBOL for mhi_get_mhi_state() bus: mhi: core: Expose mhi_get_exec_env() API for controllers bus: mhi: core: Remove unused mhi_fw_load_worker() declaration bus: mhi: core: Rename RDDM download function to use proper words bus: mhi: core: Skip RDDM download for unknown execution environment drivers/bus/mhi/core/boot.c | 15 +++++++++------ drivers/bus/mhi/core/internal.h | 2 -- drivers/bus/mhi/core/main.c | 2 ++ include/linux/mhi.h | 12 +++++++++--- 4 files changed, 20 insertions(+), 11 deletions(-) -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
