Hi all: I have got a problem while I want to open a mutex device, which has been opened by another process. such as /dev/apls9802als, which is opened while the system boot up. But I have to do some test to its read function in its driver provided to the user space. Is there a way that I can close the handler that has been opened and reopen it by the test program I write? Any hacking way for this? Thanks.

Restore of context is not done for OMAP4. This patch adds the OMAP_I2C_FLAG_RESET_REGS_POSTIDLE in the OMAP4 hwmod data which activates the restore for OMAP4. Currently the OMAP4 does not hit device off still the driver may have support for it.
