After successful sr = isl1208_i2c_set_regs(client, 0, regs, ISL1208_RTC_SECTION_LEN); sr will be 0. As a result sr = i2c_smbus_write_byte_data(client, ISL1208_REG_SR, sr & ~ISL1208_REG_SR_WRTC); is equal to sr = i2c_smbus_write_byte_data(client, ISL1208_REG_SR, 0); which clears all flags in SR. Add an additional read of SR, to have value of SR in sr again.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
