2026-01-05tee: qcomtee: mem: Fix confusing cleanup.h syntaxKrzysztof Kozlowski
Initializing automatic __free variables to NULL without need (e.g. branches with different allocations), followed by actual allocation is in contrary to explicit coding rules guiding cleanup.h: "Given that the "__free(...) = NULL" pattern for variables defined at the top of the function poses this potential interdependency problem the recommendation is to always define and assign variables in one statement and not group variable definitions at the top of the function when __free() is used." Code does not have a bug, but is less readable and uses discouraged coding practice, so fix that by moving declaration to the place of assignment.

2025-09-15tee: qcom: enable TEE_IOC_SHM_ALLOC ioctlAmirreza Zarrabi
Enable userspace to allocate shared memory with QTEE. Since QTEE handles shared memory as object, a wrapper is implemented to represent tee_shm as an object. The shared memory identifier, obtained through TEE_IOC_SHM_ALLOC, is transferred to the driver using TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF_INPUT/OUTPUT.
