The pointer obj is dereferenced in line 146 and 149 respectively, so it is not
necessary to check null again in line 149 and 175. And I have checked that all
the callers of these two functions guarantee the parameter obj passed is not
null.

The variable "str" is used as both the source and destination in
function snprintf(), which is undefined behavior based on C11. The
original description in C11 is:
"If copying takes place between objects that
overlap, the behavior is undefined."
And, the function of ceph_osdmap_state_str() is to return the osdmap
state, so it should return "doesn't exist" when all the conditions
are not satisfied. I fix it in this patch.

When it goes to error through line 144, the memory allocated to *devname is
not freed, and the caller doesn't free it either in line 250. So we free the
memroy of *devname in function cifs_compose_mount_options() when it goes to
error.

in the code generated by gen-insn-attr-x86.awk.
The author Masami Hiramutsu says here is to make both the value pointed by the
pointers and the pointers itself read-only, so we move the "const" to be after
the "*".
