HSI: omap_ssi_core: Fix error handling in ssi_init()

2022-12-31T12:32:45Z

[ Upstream commit 3ffa9f713c39a213a08d9ff13ab983a8aa5d8b5d ] The ssi_init() returns the platform_driver_register() directly without checking its return value, if platform_driver_register() failed, the ssi_pdriver is not unregistered. Fix by unregister ssi_pdriver when the last platform_driver_register() failed.

HSI: omap_ssi_core: fix possible memory leak in ssi_probe()

2022-12-31T12:32:44Z

[ Upstream commit 1aff514e1d2bd47854dbbdf867970b9d463d4c57 ] If ssi_add_controller() returns error, it should call hsi_put_controller() to give up the reference that was set in hsi_alloc_controller(), so that it can call hsi_controller_release() to free controller and ports that allocated in hsi_alloc_controller().

HSI: omap_ssi_core: fix unbalanced pm_runtime_disable()

2022-12-31T12:32:44Z

[ Upstream commit f5181c35ed7ba0ceb6e42872aad1334d994b0175 ] In error label 'out1' path in ssi_probe(), the pm_runtime_enable() has not been called yet, so pm_runtime_disable() is not needed.

HSI: nokia-modem: Replace of_gpio_count() by gpiod_count()

As a preparation to unexport of_gpio_named_count(), convert the driver to use gpiod_count() instead. Signed-off-by: Andy Shevchenko Signed-off-by: Sebastian Reichel

HSI: ssi_protocol: fix potential resource leak in ssip_pn_open()

2022-09-20T15:25:51Z

ssip_pn_open() claims the HSI client's port with hsi_claim_port(). When hsi_register_port_event() gets some error and returns a negetive value, the HSI client's port should be released with hsi_release_port(). Fix it by calling hsi_release_port() when hsi_register_port_event() fails. Signed-off-by: Jianglei Nie Signed-off-by: Sebastian Reichel

HSI: cmt_speech: Pass a pointer to virt_to_page()

2022-08-29T16:08:48Z

A pointer into virtual memory is represented by a (void *) not an u32, so the compiler warns: drivers/hsi/clients/cmt_speech.c:1092:35: warning: passing argument 1 of 'virt_to_pfn' makes pointer from integer without a cast [-Wint-conversion] Fix this with an explicit cast.

HSI: omap_ssi: Fix refcount leak in ssi_probe

2022-08-29T16:08:48Z

When returning or breaking early from a for_each_available_child_of_node() loop, we need to explicitly call of_node_put() on the child node to possibly release the node. Fixes: b209e047bc74 ("HSI: Introduce OMAP SSI driver") Signed-off-by: Miaoqian Lin Signed-off-by: Sebastian Reichel
