[PATCH AUTOSEL 5.4 038/330] mtd: cfi_cmdset_0002: don't free cfi->cfiq in error path of cfi_amdstd_setup()

[Sasha Levin]

From: Hou Tao <houtao1@xxxxxxxxxx>

[ Upstream commit 03976af89e3bd9489d542582a325892e6a8cacc0 ]

Else there may be a double-free problem, because cfi->cfiq will
be freed by mtd_do_chip_probe() if both the two invocations of
check_cmd_set() return failure.
