The sparse checker complains about converting pointers between address spaces. We correctly stored an __iomem pointer in struct scmi_optee_channel, but discarded the __iomem when returning it from get_channel_shm, causing one warning. Then we passed the non-__iomem pointer return from get_channel_shm at two other places, where an __iomem pointer is expected, causing couple of other warnings Add the appropriate __iomem annotations at all places where it is missing. optee.c:414:20: warning: incorrect type in return expression (different address spaces) optee.c:414:20: expected struct scmi_shared_mem * optee.c:414:20: got struct scmi_shared_mem [noderef] __iomem *shmem optee.c:426:26: warning: incorrect type in argument 1 (different address spaces) optee.c:426:26: expected struct scmi_shared_mem [noderef] __iomem *shmem optee.c:426:26: got struct scmi_shared_mem *shmem optee.c:441:30: warning: incorrect type in argument 1 (different address spaces) optee.c:441:30: expected struct scmi_shared_mem [noderef] __iomem *shmem optee.c:441:30: got struct scmi_shared_mem *shmem Link: https://lore.kernel.org/r/20220404102419.1159705-1-sudeep.holla@arm.com Cc: Etienne Carriere <etienne.carriere@linaro.org> Cc: Cristian Marussi <cristian.marussi@arm.com> Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Sudeep Holla <sudeep.holla@arm.com> |
