2021-04-12s390/pci: narrow scope of zpci_configure_device()Niklas Schnelle
Currently zpci_configure_device() can be called on a zPCI function in two completely different states. Either the underlying zPCI function has already been configured by the platform and we are only doing the scanning to get it usable by Linux drivers. Or the underlying function is in Standby and we first do an SCLP to get it configured. This makes zpci_configure_device() harder to reason about. Since calling zpci_configure_device() on a function in Standby only happens in enable_slot() simply pull out the SCLP call and setting of zdev->state and thus call zpci_configure_device() under the same circumstances as in the event handling code.

This also allows user space to figure out which pins are available through the chardev interface without having to request each pin in turn. Note that the return value when requesting an unavailable pin will now be -EINVAL instead of -ENODEV.

2021-04-12dmaengine: Fix a double free in dma_async_device_registerLv Yunlong
In the first list_for_each_entry() macro of dma_async_device_register, it gets the chan from list and calls __dma_async_device_channel_register (..,chan). We can see that chan->local is allocated by alloc_percpu() and it is freed chan->local by free_percpu(chan->local) when __dma_async_device_channel_register() failed. But after __dma_async_device_channel_register() failed, the caller will goto err_out and freed the chan->local in the second time by free_percpu(). The cause of this problem is forget to set chan->local to NULL when chan->local was freed in __dma_async_device_channel_register(). My patch sets chan->local to NULL when the callee failed to avoid double free.

2021-04-11bcache: reduce redundant code in bch_cached_dev_run()Zhiqiang Liu
In bch_cached_dev_run(), free(env[1])|free(env[2])|free(buf) show up three times. This patch introduce out tag in which free(env[1])|free(env[2])|free(buf) are only called one time. If we need to call free() when errors occur, we can set error code to ret, and then goto out tag directly.

2021-04-11Revert "mtd: spi-nor: macronix: Add support for mx25l51245g"Tudor Ambarus
This reverts commit 04b8edad262eec0d153005973dfbdd83423c0dcb. mx25l51245g and mx66l51235l have the same flash ID. The flash detection returns the first entry in the flash_info array that matches the flash ID that was read, thus for the 0xc2201a ID, mx25l51245g was always hit, introducing a regression for mx66l51235l. If one wants to differentiate the flash names, a better fix would be to differentiate between the two at run-time, depending on SFDP, and choose the correct name from a list of flash names, depending on the SFDP differentiator.

2021-04-11mtd: spi-nor: core: Fix an issue of releasing resources during read/writeXiang Chen
If rmmod the driver during read or write, the driver will release the resources which are used during read or write, so it is possible to refer to NULL pointer. Use the testcase "mtd_debug read /dev/mtd0 0xc00000 0x400000 dest_file & sleep 0.5;rmmod spi_hisi_sfc_v3xx.ko", the issue can be reproduced in hisi_sfc_v3xx driver. To avoid the issue, fill the interface _get_device and _put_device of mtd_info to grab the reference to the spi controller driver module, so the request of rmmod the driver is rejected before read/write is finished.
