2021-03-04T09:26:48+00:00

commit fe6653460ee7a7dbe0cd5fd322992af862ce5ab0 upstream. Put the child node np when it fails to get or register device.

mtd: spi-nor: core: Add erase size check for erase command initialization

2021-03-04T09:26:48+00:00

commit 58fa22f68fcaff20ce4d08a6adffa64f65ccd37d upstream. Even if erase type is same as previous region, erase size can be different if the previous region is overlaid region. Since 'region->size' is assigned to 'cmd->size' for overlaid region, comparing 'erase->size' and 'cmd->size' can detect previous overlaid region.

mtd: spi-nor: core: Fix erase type discovery for overlaid region

2021-03-04T09:26:48+00:00

commit 969b276718de37dfe66fce3a5633f611e8cd58fd upstream. In case of overlaid regions in which their biggest erase size command overpasses in size the region's size, only the non-overlaid portion of the sector gets erased. For example, if a Sector Erase command is applied to a 256-kB range that is overlaid by 4-kB sectors, the overlaid 4-kB sectors are not affected by the erase. For overlaid regions, 'region->size' is assigned to 'cmd->size' later in spi_nor_init_erase_cmd(), so 'erase->size' can be greater than 'len'.

mtd: spi-nor: sfdp: Fix wrong erase type bitmask for overlaid region

2021-03-04T09:26:48+00:00

commit abdf5a5ef9652bad4d58058bc22ddf23543ba3e1 upstream. At the time spi_nor_region_check_overlay() is called, the erase types are sorted in ascending order of erase size. The 'erase_type' should be masked with 'BIT(erase[i].idx)' instead of 'BIT(i)'.

mtd: spi-nor: sfdp: Fix last erase region marking

commit 9166f4af32db74e1544a2149aef231ff24515ea3 upstream. The place of spi_nor_region_mark_end() must be moved, because 'i' is re-used for the index of erase[].

spi: cadence-quadspi: Abort read if dummy cycles required are too many

2021-03-04T09:26:27+00:00

[ Upstream commit ceeda328edeeeeac7579e9dbf0610785a3b83d39 ] The controller can only support up to 31 dummy cycles. If the command requires more it falls back to using 31. This command is likely to fail because the correct number of cycles are not waited upon. Rather than silently issuing an incorrect command, fail loudly so the caller can get a chance to find out the command can't be supported by the controller.

mtd: parsers: afs: Fix freeing the part name memory in failure

[ Upstream commit 7b844cf445f0a7daa68be0ce71eb2c88d68b0c5d ] In the case of failure while parsing the partitions, the iterator should be pre decremented by one before starting to free the memory allocated by kstrdup(). Because in the failure case, kstrdup() will not succeed and thus no memory will be allocated for the current iteration.

Revert "mtd: spinand: Fix OOB read"

2021-01-09T12:44:54+00:00

This reverts stable commit baad618d078c857f99cc286ea249e9629159901f. This commit is adding lines to spinand_write_to_cache_op, wheras the upstream commit 868cbe2a6dcee451bd8f87cbbb2a73cf463b57e5 that this was supposed to backport was touching spinand_read_from_cache_op. It causes a crash on writing OOB data by attempting to write to read-only kernel memory. Cc: Miquel Raynal Signed-off-by: Felix Fietkau Signed-off-by: Greg Kroah-Hartman
