Switch to using the SIMPLE_DEV_PM_OPS macro to declare the driver's pm_ops. It reduces code size. Also, CONFIG_PM_SLEEP is added to prevent build warning when CONFIG_PM_SLEEP is not selected. Signed-off-by:

Instead of using legacy suspend/resume methods, using newer dev_pm_ops structure allows better control over power management. Also, 'wake_en' variable is moved, because it is only used when CONFIG_PM_SLEEP is enabled. Signed-off-by:

The rtc-ds1307 driver does not properly handle block operations bigger than 32 bytes in either of the two modes supported (SMbus native, or emulated if not supported by the SMbus platform driver). It also does not properly handle userland-supplied input (block operation length) through sysfs and may suffer a type of buffer overrun. The driver has been modified with proper input validation, buffer sizes, and now splits block transfers bigger than 32 bytes into separate transfers. Explanation : Buffer size allocated is I2C_SMBUS_BLOCK_MAX which equals to 32 as per the SMbus spec. Reads and write may be up to 56 bytes (to the NVRAM). This patch allocated a 255 byte buffer, the maximum allowable (address is an u8). It's not only a buffer problem, SMbus only supports up to 32 bytes transfer at once, so it's needed to split bigger transfers. Patch successfully tested on 3.2.27; cleanly applies on 3.7-rc4.
