eeprom: 93xx46: Fix SPI device leak

2016-05-01T21:04:19Z

The 93xx46 driver is using spi_dev_get() apparently just to take a copy of the SPI device used to instantiate it but never calls spi_dev_put() to free it. Since the device is guaranteed to exist between probe() and remove() there should be no need for the driver to take an extra reference to it so fix the leak by just using a straight assignment.

eeprom: at24: replace msleep() with usleep_range()

2016-04-16T20:57:22Z

We cannot expect msleep(1) to actually sleep for a period shorter than 20 ms. Replace all calls to msleep() with usleep_range(). Signed-off-by: Bartosz Golaszewski Signed-off-by: Wolfram Sang

The second check for I2C_FUNC_I2C is reduntant, so remove it. Signed-off-by: Bartosz Golaszewski [wsa: reworded commit message] Signed-off-by: Wolfram Sang

misc: at24: replace memory_accessor with nvmem_device_read

2016-03-02T00:55:48Z

Now that the AT24 uses the NVMEM framework, replace the memory_accessor in the setup() callback with nvmem API calls. Signed-off-by: Andrew Lunn Acked-by: Srinivas Kandagatla Tested-by: Sekhar Nori Acked-by: Wolfram Sang Signed-off-by: Greg Kroah-Hartman

eeprom: 93xx46: extend driver to plug into the NVMEM framework

2016-03-02T00:55:48Z

Add a regmap for accessing the EEPROM, and then use that with the NVMEM framework. Enable backward compatibility in the NVMEM config structure, so that the 'eeprom' file in sys is provided by the framework. Signed-off-by: Andrew Lunn Acked-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman
