14 is the index, 128 is the element size, so this is now an "offset".

You shouldn't need to initialize smem_blk_sz if you check the return
value of qcom_smem_get() first.

80 chars is just a guideline and this looks prettier if you avoid the
line wrap. That said, if you pick shorter names for smem_tbl_ptr and
smem_blk_sz you probably even have to worry.

In English you're trying to determine: "did qcom_smem_get() return a
valid pointer and is the item's size at least as big as we need".

So just write that in C:

if (smem_tbl_ptr && smem_blk_sz >= SMEM_IMG_INDEX_VENUS + VER_STR_SZ)

> + memcpy(smem_tbl_ptr + SMEM_IMG_INDEX_VENUS,

Again, please avoid the line wrap...

Bjorn

Hi Bjorn,

Thanks for your review comments.
I have addressed all in the latest patch v3.
couldn't think of a shorter name for variables without losing the
readability so kept as it is.

Thanks,
Dikshita
