* i2c_probe: limit slave addresses to [0x04, 0x77]Uwe Kleine-König2019-01-281-4/+6
| | | | | | | | | | | | | | | Adresses below 0x04 and above 0x77 are reserved in the i2c bus specification, so don't probe these addresses unless requested explicitly. Also do more strict boundary checking: - ensure start address is greater or equal to zero; - don't decrease stopaddr after checking it being greater or equal to startaddr.

* ls: Adjust amount of space allocated for filesizeAndrey Smirnov2019-01-241-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maximum file size on 64-bit system is 2^63-1 (9223372036854775807), which takes more that 14 characters of space. In order to keep things properly aligned adjust that spacing to 20 on 64-bit platforms.

* mount command: Fix "mount /dev/<devname>"Sascha Hauer2018-11-211-1/+3

Since 8ca7053b3ff we only put the device name into device_detect_by_name(), but cdev_by_name() still gets the full path. The result is that a "mount /dev/<devname>" no longer works. Fix this.

With this commit an unwanted free(data) on the freshly set property value is done if someone tries to set the value of an already present property (not the case for a new property). Furthermore in fixup mode the pointer fixup->data is freed when the fixup function is called more than once. This leads to a hanging system after calling of_dump -F many times. Fix this issues by copying the data to a new allocated memory area like a new property is created.
