Subject: staging: speakup: i18n.c: Fix leak in msg_set()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fafbc202cd3c6ff1dc77430176c4c41102ebbdfd;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

staging: speakup: i18n.c: Fix leak in msg_set()

If we end up returning -EINVAL from the function we will leak the
memory allocated to 'newstr' which has been allocated but not yet
assigned to anything.
Fix the leak by properly freeing the memory again before we return.
