Merge tag 'spi-v4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown: "This release is almost entirely driver changes, there's a couple of fixes in the core but otherwise it's all drivers: - fix for mixed dynamic and static bus number assignment. - fixes for some leaks arising from confusing lifetime rules during device unregistration and improved documentation to try to help avoid this in the future. - fixes to make the native chip select support for i.MX usable. - slave mode support for i.MX. - support for Coldfire MCF5441x DSPI, Renesas R8A7443/5 and Spreadtrum ADI" * tag 'spi-v4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (31 commits) spi: imx: Don't require platform data chipselect array spi: imx: Fix failure path leak on GPIO request error spi: imx: GPIO based chip selects should not be required spi: sh-msiof: remove redundant pointer dev spi: s3c64xx: remove redundant pointer sci spi: spi-fsl-dspi: enabling Coldfire mcf5441x dspi spi: fix IDR collision on systems with both fixed and dynamic SPI bus numbers spi: orion: remove redundant assignment of status to zero spi: sh-msiof: Fix DMA transfer size check spi: imx: Fix failure path leak on GPIO request error spi: spi-axi: fix potential use-after-free after deregistration spi: document odd controller reference handling spi: fix use-after-free at controller deregistration spi: sprd: Fix the possible negative value of BIT() spi: sprd-adi: fix platform_no_drv_owner.cocci warnings spi: a3700: Change SPI mode before asserting chip-select spi: tegra114: correct register name in definition spi: spreadtrum adi: add hwspinlock dependency spi: sh-msiof: Use of_device_get_match_data() helper spi: rspi: Use of_device_get_match_data() helper ...
