3.16.50-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Arnd Bergmann <[email protected]> commit 906b268477bc03daaa04f739844c120fe4dbc991 upstream. kernelci.org reports a warning for this driver, as it copies a local variable into a 'const char *' string: drivers/mtd/maps/pmcmsp-flash.c:149:30: warning: passing argument 1 of 'strncpy' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers] Using kstrndup() simplifies the code and avoids the warning.
