Subject: net/9p/protocol.c: Fix a memory leak
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1b0bcbcf62884959fa7214eb16c44cff445691c6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

net/9p/protocol.c: Fix a memory leak

When p9pdu_readf() is called with "s" attribute, it allocates a pointer that
will store a string. In p9dirent_read(), this pointer is not being released,
leading to out of memory errors.
This patch releases this pointer after string is copyed to dirent->d_name.
