cpufreq: interactive: fix compiling warnings

The gcc warns like:

  cpufreq_interactive.c:745:6: warning: operation on 'ret' may be
undefined [-Wsequence-point]

It was introduced by commit cf0fad49d17cb8273ce555dd5b7afab67d7923bf.

Since sprintf(...) just return 1 (one character) in this case, ret
should not changed.
Just discarding the result of sprintf(...) leads to the result that
the committer of cf0fad49d17cb8273ce555dd5b7afab67d7923bf wants.

passed to the memory allocators.

msm: kgsl: avoid zero length scatterlist allocation

During sglist allocation we calculate sglen as
per below

sglen_alloc = PAGE_ALIGN(size) >> PAGE_SHIFT;

sglen_alloc can be zero if size falls within the
last page. For example, when size = 0xFFFF_FF7B,
PAGE_ALIGN(0xFFFF_FF7B) will be 0, considering
0x1000 (4kb) PAGE_SIZE. if kzalloc() with
zero size, it will return ZERO_SIZE_PTR which is
not NULL and we always do NULL check. Dereferencing
ZERO_SIZE_PTR will lead to a distinct access fault.
