mmc: use octal file permissions instead of symbolic

2025-10-21T11:37:38+00:00

As stated in Documentation/dev-tools/checkpatch.rst, octal file permissions are preferred over symbolic constants because they are easier to read and understand. Replace symbolic permissions with their octal equivalents. Signed-off-by: Pedro Demarchi Gomes Signed-off-by: Ulf Hansson

mmc: core: constify the struct device_type usage

2024-02-27T12:48:36+00:00

Since commit aed65af1cc2f ("drivers: make device_type const"), the driver core can properly handle constant struct device_type. Move the sdio_type, sd_type and mmc_type variables to be constant structures as well, placing it into read-only memory which can not be modified at runtime.

mmc: core: use sysfs_emit() instead of sprintf()

2022-02-28T12:06:23+00:00

sprintf() (still used in the MMC core for the sysfs output) is vulnerable to the buffer overflow. Use the new-fangled sysfs_emit() instead. Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.

mmc: core: Move public functions from card.h to private headers

2017-02-13T12:20:24+00:00

A significant amount of functions and other definitions are available through the public mmc card.h header file. Let's slim down this public mmc interface, as to prevent users from abusing it, by moving some of the functions/definitions to private mmc header files. This change concentrates on moving the functions into private mmc headers, following changes may continue with additional clean-ups.

mmc: core: First step in cleaning up private mmc header files

2017-02-13T12:20:20+00:00

This is the first step in cleaning up the private mmc header files. In this change we makes sure each header file builds standalone, as that helps to resolve dependencies. While changing this, it also seems reasonable to stop including other headers from inside a header itself which it don't depend upon. Additionally, in some cases such dependencies are better resolved by forward declaring the needed struct. Signed-off-by: Ulf Hansson Reviewed-by: Shawn Lin

mmc: make mmc_dev_to_card() macro public

Conversion from struct device to struct mmc_card is used more than in one place. Due to this it's better to have public macro for such thing. Signed-off-by: Andy Shevchenko Cc: Adrian Hunter Cc: Signed-off-by: Andrew Morton Signed-off-by: Chris Ball

mmc: use sysfs groups to handle conditional attributes

2008-03-23T00:02:20+00:00

Suppressing uevents turned out to be a bad idea as it screws up the order of events, making user space very confused. Change the system to use sysfs groups instead. This is a regression that, for some odd reason, has gone unnoticed for some time. It confuses hal so that the block devices (which have the mmc device as a parent) are not registered. End result being that desktop magic when cards are inserted won't work. Signed-off-by: Pierre Ossman Signed-off-by: Linus Torvalds

mmc: refactor bus operations

Move bus operations to its own file for the sake of clarity. Also delegate sysfs attributes to bus handlers in preparation for other more exotic types. Signed-off-by: Pierre Ossman
