spi: omap2-mcspi: Fix the IS_ERR() bug for devm_clk_get_optional_enabled()

2024-12-05T11:32:26Z

The devm_clk_get_optional_enabled() function returns error pointers(PTR_ERR()). So use IS_ERR() to check it. Verified on K3-J7200 EVM board, without clock node mentioned in the device tree.

module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

spi: mpc52xx: Add cancel_work_sync before module remove

2024-12-02T00:29:46Z

If we remove the module which will call mpc52xx_spi_remove it will free 'ms' through spi_unregister_controller. while the work ms->work will be used. The sequence of operations that may lead to a UAF bug. Fix it by ensuring that the work is canceled before proceeding with the cleanup in mpc52xx_spi_remove.

spi: atmel-quadspi: Fix register name in verbose logging function

2024-11-26T11:29:09Z

`atmel_qspi_reg_name()` is used for pretty-printing register offsets for verbose logging of register accesses. However, due to a typo (likely a copy-paste error), QSPI_RD's offset prints as "MR", the name of the previous register. Fix this typo.

Pull MTD updates from Miquel Raynal: "MTD device changes: - switch platform_driver back to remove() - misc fixes SPI-NAND changes: - a load of fixes to Winbond manufacturer driver - structure constification Raw NAND changes: - improve the power management of the GPMI driver - Davinci driver clean-ups - fix leak in the Atmel driver - fix some typos in the core SPI NOR changes: - Introduce byte swap support for 8D-8D-8D mode and a user for it: macronix. SPI NOR flashes may swap the bytes on a 16-bit boundary when configured in Octal DTR mode. For such cases the byte order is propagated through SPI MEM to the SPI controllers so that the controllers swap the bytes back at runtime. This avoids breaking the boot sequence because of the endianness problems that appear when the bootloaders use 1-1-1 and the kernel uses 8D-8D-8D with byte swap support. Along with the SPI MEM byte swap support we queue a patch for the SPI MXIC controller that swaps the bytes back at runtime" * tag 'mtd/for-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux: (25 commits) mtd: spi-nor: core: replace dummy buswidth from addr to data mtd: spi-nor: winbond: add "w/ and w/o SFDP" comment mtd: spi-nor: spansion: Use nor->addr_nbytes in octal DTR mode in RD_ANY_REG_OP mtd: Switch back to struct platform_driver::remove() mtd: cfi_cmdset_0002: remove redundant assignment to variable ret mtd: spinand: Constify struct nand_ecc_engine_ops MAINTAINERS: add mailing list for GPMI NAND driver mtd: spinand: winbond: Sort the devices mtd: spinand: winbond: Ignore the last ID characters mtd: spinand: winbond: Fix 512GW, 01GW, 01JW and 02JW ECC information mtd: spinand: winbond: Fix 512GW and 02JW OOB layout mtd: nand: raw: gpmi: improve power management handling mtd: nand: raw: gpmi: switch to SYSTEM_SLEEP_PM_OPS mtd: rawnand: davinci: use generic device property helpers mtd: rawnand: davinci: break the line correctly mtd: rawnand: davinci: order headers alphabetically mtd: rawnand: atmel: Fix possible memory leak mtd: rawnand: Correct multiple typos in comments mtd: hyperbus: rpc-if: Add missing MODULE_DEVICE_TABLE mtd: spi-nor: add support for Macronix Octal flash ...
