2024-01-18bcachefs: Replace strlcpy() with strscpy()Kees Cook
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated[1]. Additionally, it returns the size of the source string, not the resulting size of the destination string. In an effort to remove strlcpy() completely[2], replace strlcpy() here with strscpy(). Nothing checks the return value here, so a direct replacement with strspy() is possible.

2024-01-18i2c: stm32f7: add support for stm32mp25 socAlain Volmat
The stm32mp25 has only a single interrupt line used for both events and errors. In order to cope with that, reorganise the error handling code so that it can be called either from the common handler (used in case of SoC having only a single IT line) and the error handler for others. The CR1 register also embeds a new FMP bit, necessary when running at Fast Mode Plus frequency. This bit should be used instead of the SYSCFG bit used on other platforms. Add a new compatible to distinguish between the SoCs and two boolean within the setup structure in order to know if the platform has a single/multiple IT lines and if the FMP bit within CR1 is available or not.

2024-01-18i2c: stm32f7: perform most of irq job in threaded handlerAlain Volmat
The irq handling is currently split between the irq handler and the threaded irq handler. Some of the handling (such as dma related stuffs) done within the irq handler might sleep or take some time leading to issues if the kernel is built with realtime constraints. In order to fix that, perform an overall rework to perform most of the job within the threaded handler and only keep fifo access in the non threaded handler.
