With gcc-4.1.2:
net/smc/smc_core.c: In function ‘__smc_buf_create’:
net/smc/smc_core.c:567: warning: ‘bufsize’ may be used uninitialized in this function
Indeed, if the for-loop is never executed, bufsize is used
uninitialized. In addition, buf_desc is stored for later use, while it
is still a NULL pointer.
Before, error handling was done by checking if buf_desc is non-NULL.
The cleanup changed this to an error check, but forgot to update the
preinitialization of buf_desc to an error pointer.
Update the preinitializatin of buf_desc to fix this.
Fixes: b33982c3a6 ("net/smc: cleanup function __smc_buf_create()")
