Storing a bogus i2c_client structure on the stack adds overhead and causes a compile-time warning: drivers/tee/optee/rpc.c:493:6: error: stack frame size of 1056 bytes in function 'optee_handle_rpc' [-Werror,-Wframe-larger-than=] void optee_handle_rpc(struct tee_context *ctx, struct optee_rpc_param *param, Change the implementation of handle_rpc_func_cmd_i2c_transfer() to open-code the i2c_transfer() call, which makes it easier to read and avoids the warning.

of_match_node() calls __of_match_node() which loops though the entries of matches array. It stops when condition: (matches->name[0] || matches->type[0] || matches->compatible[0]) is false. Thus, add a null entry at the end of at91_soc_allowed_list[] array.

2021-01-25memory: ti-aemif: Drop child node when jumping out loopPan Bian
Call of_node_put() to decrement the reference count of the child node child_np when jumping out of the loop body of for_each_available_child_of_node(), which is a macro that increments and decrements the reference count of child node. If the loop is broken, the reference of the child node should be dropped manually.

2021-01-25reset: Add devm_reset_control_get_optional_exclusive_released()Dmitry Osipenko
NVIDIA Tegra DRM and media drivers will need a resource-managed-optional variant of reset_control_get_exclusive_released() in order to switch away from a legacy Tegra-specific PD API to a GENPD API without much hassle. Add the new reset helper to the reset API.

2021-01-23memory: tegra: Check whether reset is already assertedDmitry Osipenko
Check whether memory client reset is already asserted in order to prevent DMA-flush error on trying to re-assert an already asserted reset. This becomes a problem once PMC GENPD is enabled to use memory resets since GENPD will get a error and fail to toggle power domain. PMC GENPDs can't be toggled safely without holding memory reset on Tegra and we're about to fix this.

Apart from that, we just have a minor fix in scmi_remove which was found recently as we are now experimenting more on SCMI as module.
