memory: Explicitly include correct DT includes

2023-07-25T20:09:37+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

memory: remove MODULE_LICENSE in non-modules

2023-03-09T14:20:50+00:00

Since commit 8b41fc4454e3 ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

memory: fsl_ifc: populate child nodes of buses and mfd devices

2022-04-06T07:39:16+00:00

Commit 3e25f800afb8 ("memory: fsl_ifc: populate child devices without relying on simple-bus") was trying to replace the "simple-bus" compatible with explicit bus populate in the driver. But of_platform_populate() only populates child nodes of ifc without populating child buses and child mfd devices residing under ifc. Change it to of_platform_default_populate() to fix the problem.

After we update the binding to not use simple-bus compatible for the controller, we need the driver to populate the child devices explicitly. Signed-off-by: Li Yang Link: https://lore.kernel.org/r/20211116211846.16335-3-leoyang.li@nxp.com Signed-off-by: Krzysztof Kozlowski

memory: fsl_ifc: fix leak of irq and nand_irq in fsl_ifc_ctrl_probe

2021-10-07T18:39:17+00:00

The error handling code of fsl_ifc_ctrl_probe is problematic. When fsl_ifc_ctrl_init fails or request_irq of fsl_ifc_ctrl_dev->irq fails, it forgets to free the irq and nand_irq. Meanwhile, if request_irq of fsl_ifc_ctrl_dev->nand_irq fails, it will still free nand_irq even if the request_irq is not successful. Fix this by refactoring the error handling code.
