The problem is that kobject_add_internal() first adds a kobject to the kset and then try to create sysfs directory for it. If the creation fails, it remove the kobject from the kset. get_device_parent() accesses class_dirs kset while only holding class_dirs.list_lock to see whether the cuse class dir exists. But when it exists, it may not have finished initialization yet or may fail and get removed soon. In the above case, the former happened so the second one ends up trying to create subdirectory under NULL sysfs_dirent. Fix it by grabbing a mutex in get_device_parent().

Beside in i2c_pnx_start and i2c_pnx_stop the start/stop bit are also set during the transfer of a i2c message in the master_xmit/rcv calls. This is wrong since we can't set the start/stop condition during the transaction of a single message any way. As a matter of fact, the driver will sometimes set both the start and the stop bits at one time. This can be easily reproduced by sending a simple read request like e.g struct i2c_msg msgs[] = { { addr, 0, 1, buf }, { addr, I2C_M_RD, offset, buf } }; While processing the first message the i2c_pnx_master_xmit will set both the start_bit and the stop_bit, which will eventually confuse the slave.

| 53dbab7 | Haojian Zhuang | 08 January 2010, 11:01:24 UTC | mfd: Support 88pm8606 in 860x driver 88PM8606 and 88PM8607 are two discrete chips used for power management. Hardware designer can use them together or only one of them according to requirement. There's some logic tightly linked between these two chips. For example, USB charger driver needs to access both chips by I2C interface. Now share one driver to these two devices. Only one I2C client is identified in platform init data. If another chip is also used, user should mark it in companion_addr field of platform init data. Then driver could create another I2C client for the companion chip. All I2C operations are accessed by 860x-i2c driver. In order to support both I2C client address, the read/write API is changed in below. reg_read(client, offset) reg_write(client, offset, data) The benefit is that client drivers only need one kind of read/write API. I2C and MFD driver can be shared in both 8606 and 8607. Since API is changed, update API in 8607 regulator driver.

| 0e820ab | Julia Lawall | 22 December 2009, 20:31:43 UTC | mfd: Correct use after free for t7l66xb The structure t7l66xb should not be freed before the subsequent references to its fields in the arguments to clk_put. Furthermore, this structure is allocated near the beginning of the function, and a goto to the label err_noirq appears after a successful allocation, so it would seem that the kfree should be moved down below this label. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,e; identifier f; iterator I; statement S; @@ *kfree(x); ... when != &x when != x = e when != I(x,...)
