ARM: 9445/1: clkdev: Mark some functions with __printf() attribute

2025-03-26T13:31:49+00:00

Some of the functions are using printf() type of format, and compiler is not happy about them as is: clkdev.c:185:17: error: function ‘vclkdev_alloc’ might be a candidate for gnu_printf’ format attribute [-Werror=suggest-attribute=format] clkdev.c:224:9: error: function ‘vclkdev_create’ might be a candidate for gnu_printf’ format attribute [-Werror=suggest-attribute=format] clkdev.c:314:9: error: function ‘__clk_register_clkdev’ might be a candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format] Fix the compilation errors by adding __printf() attributes.

clkdev: don't fail clkdev_alloc() if over-sized

2024-06-04T16:12:01+00:00

Don't fail clkdev_alloc() if the strings are over-sized. In this case, the entry will not match during lookup, so its useless. However, since code fails if we return NULL leading to boot failure, return a dummy entry with the connection and device IDs set to "bad". Leave the warning so these problems can be found, and the useless wasteful clkdev registrations removed.

clkdev: report over-sized strings when creating clkdev entries

2024-05-08T15:26:30+00:00

Report an error when an attempt to register a clkdev entry results in a truncated string so the problem can be easily spotted. Reported by: Duanqiang Wen Signed-off-by: Russell King (Oracle)

clkdev: Update clkdev id usage to allow for longer names

2024-02-28T22:14:44+00:00

clkdev DEV ID information is limited to an array of 20 bytes (MAX_DEV_ID). It is possible that the ID could be longer than that. If so, the lookup will fail because the "real ID" will not match the copied value. For instance, generating a device name for the I2C Designware module using the PCI ID can result in a name of: i2c_designware.39424 clkdev_create() will store: i2c_designware.3942 The stored name is one off and will not match correctly during probe. Increase the size of the ID to allow for a longer name. Reviewed-by: Russell King (Oracle) Signed-off-by: Michael J.

clkdev: Simplify devm_clk_hw_register_clkdev() function

2022-09-30T21:50:11+00:00

Use devm_add_action_or_reset() instead of devres_alloc() and devres_add(), which works the same. This will simplify the code. There is no functional changes.

clk: move from strlcpy with unused retval to strscpy

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

clkdev: remove unused clkdev_alloc() interfaces

2021-06-08T15:00:09+00:00

The last user of clkdev_alloc() and clkdev_hw_alloc() was removed last year, so everything now calls clkdev_create() and clkdev_hw_create() instead. Removing the unused functions lets the compiler optimize the remaining ones slightly better.
