Title
mmc: core: use sysfs_emit() instead of sprintf()
Summary
In the Linux kernel, the following vulnerability has been resolved:
mmc: core: use sysfs_emit() instead of sprintf()
sprintf() (still used in the MMC core for the sysfs output) is vulnerable
to the buffer overflow. Use the new-fangled sysfs_emit() instead.
Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool.
