Since commit 8871e99f ('asus-laptop: HRWS/HWRS typo'), module
initialisation is very slow on the Asus UL30A.  The HWRS method takes
about 12 seconds to run, and subsequent initialisation also seems to
be delayed.  Since we don't really need the result, don't bother
calling it on init.  Those who are curious can still get the result
through the 'infos' device attribute.

Update the comment about HWRS in show_infos().

SN06 in some cases returns an Integer instead of a buffer. While the
code handling the return value was trying to cope with the difference,
the memcpy call was not making any difference between the two types of
acpi_object union. This regression was introduced in 3.5.
While there also rework the return value logic to improve readability.

print_prefix() passes a NULL buf to print_time() to get the length of
the time prefix; when printk times are enabled, the current code just
returns the constant 15, which matches the format "[%5lu.%06lu] " used
to print the time value.  However, this is obviously incorrect when the
whole seconds part of the time gets beyond 5 digits (100000 seconds is a
bit more than a day of uptime).

The simple fix is to use snprintf(NULL, 0, ...) to calculate the actual
length of the time prefix.  This could be micro-optimized but it seems
better to have simpler, more readable code here.

The bug leads to the syslog system call miscomputing which messages fit
into the userspace buffer.  If there are enough messages to fill
log_buf_len and some have a timestamp >= 100000, dmesg may fail with:

    # dmesg
    klogctl: Bad address

When this happens, strace shows that the failure is indeed EFAULT due to
the kernel mistakenly accessing past the end of dmesg's buffer, since
dmesg asks the kernel how big a buffer it needs, allocates a bit more,
and then gets an error when it asks the kernel to fill it:

    syslog(0xa, 0, 0)                       = 1048576
    mmap(NULL, 1052672, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fa4d25d2000
    syslog(0x3, 0x7fa4d25d2010, 0x100008)   = -1 EFAULT (Bad address)

As far as I can see, the bug has been there as long as print_time(),
which comes from commit 084681d1 ("printk: flush continuation lines
immediately to console") in 3.5-rc5.
