[PATCH] staging: rtl8723bs: fix missing status update on sdio_alloc_irq() failure

by Liang Jie

From: Liang Jie <liangjie(a)lixiang.com> The return value of sdio_alloc_irq() was not stored in status. If sdio_alloc_irq() fails after rtw_drv_register_netdev() succeeds, status remains _SUCCESS and the error path skips resource cleanup, while rtw_drv_init() still returns success. Store the return value of sdio_alloc_irq() in status and reuse the existing error handling which relies on status.

[PATCH 6.18 regression fix] dma-mapping: Fix DMA_BIT_MASK() macro being broken

by Hans de Goede

After commit a50f7456f853 ("dma-mapping: Allow use of DMA_BIT_MASK(64) in global scope"), the DMA_BIT_MASK() macro is broken when passed non trivial statements for the value of 'n'. This is caused by the new version missing parenthesis around 'n' when evaluating 'n'. One example of this breakage is the IPU6 driver now crashing due to it getting DMA-addresses with address bit 32 set even though it has tried to set a 32 bit DMA mask. The IPU6 CSI2 engine has a DMA mask of either 31 or 32 bits depending on if it is in secure mode or not and it sets this masks like this: mmu_info->aperture_end = (dma_addr_t)DMA_BIT_MASK(isp->secure_mode ? IPU6_MMU_ADDR_BITS : IPU6_MMU_ADDR_BITS_NON_SECURE); So the 'n' argument here is "isp->secure_mode ? IPU6_MMU_ADDR_BITS : IPU6_MMU_ADDR_BITS_NON_SECURE" which gets expanded into: isp->secure_mode ? IPU6_MMU_ADDR_BITS : IPU6_MMU_ADDR_BITS_NON_SECURE - 1 With the -1 only being applied in the non secure case, causing the secure mode mask to be one 1 bit too large.

[PATCH] reset: gpio: suppress bind attributes in sysfs

by Bartosz Golaszewski

This is a special device that's created dynamically and is supposed to stay in memory forever. We also currently don't have a devlink between it and the actual reset consumer. Suppress sysfs bind attributes so that user-space can't unbind the device because - as of now - it will cause a use-after-free splat from any user that puts the reset control handle.
