Denis Osterland 5b9fc795f9 rtc: isl1208: Fix unintended clear of SR bits
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.
