misc: eeprom/idt_89hpesx: Use devm_kmemdup to replace devm_kmalloc + memcpy

2023-08-11T19:38:52+00:00

Use the helper function devm_kmemdup() rather than duplicating its implementation, which helps to enhance code readability. Signed-off-by: Li Zetao Reviewed-by: Luca Ceresoli Link: https://lore.kernel.org/r/20230810115049.2104099-1-lizetao1@huawei.com Signed-off-by: Greg Kroah-Hartman

misc: Switch i2c drivers back to use .probe()

2023-05-29T14:04:52+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver. While touching these drivers, fix alignment in apds990x.c and bh1770glc.c.

eeprom: idt_89hpesx: Fix error handling in idt_init()

2023-01-20T11:05:26+00:00

A problem about idt_89hpesx create debugfs failed is triggered with the following log given: [ 4973.269647] debugfs: Directory 'idt_csr' with parent '/' already present! The reason is that idt_init() returns i2c_add_driver() directly without checking its return value, if i2c_add_driver() failed, it returns without destroy the newly created debugfs, resulting the debugfs of idt_csr can never be created later. idt_init() debugfs_create_dir() # create debugfs directory i2c_add_driver() driver_register() bus_add_driver() priv = kzalloc(...) # OOM happened # return without destroy debugfs directory Fix by removing debugfs when i2c_add_driver() returns error.
