Hello Hariprasad Shenai,
This is a semi-automatic email about new static checker warnings.
The patch 324429d74127: "chcr: Support for Chelsio's Crypto Hardware"
from Aug 17, 2016, leads to the following Smatch complaint:
drivers/crypto/chelsio/chcr_algo.c:378 write_sg_data_page_desc()
error: we previously assumed 'sg' could be null (see line 376)
drivers/crypto/chelsio/chcr_algo.c
375 while (count > 0) {
376 if (sg && (!(sg->length)))
^^
Check.
377 break;
378 spage = sg_page(sg);
^^^^^^^^^^^
Unchecked dereference inside function.
379 get_page(spage);
380 page_len = min(sg->length, count);
regards,
dan carpenter
