Subject: pstore: Fix memory leak when decompress using big_oops_buf
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e32634f5d57f1dce88624b70a6d625915f6ea09e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

pstore: Fix memory leak when decompress using big_oops_buf

After sucessful decompressing, the buffer which pointed by 'buf' will be
lost as 'buf' is overwrite by 'big_oops_buf' and will never be freed.
