+Subject: crypto: memneq - move into lib/
+
+From: Jason A. Donenfeld <Jason@zx2c4.com>
+
+commit abfed87e2a12bd246047d78c01d81eb9529f1d06 upstream.
+
+This is used by code that doesn't need CONFIG_CRYPTO, so move this into
+lib/ with a Kconfig option so that it can be selected by whatever needs
+it.
+
+This fixes a linker error Zheng pointed out when
+CRYPTO_MANAGER_DISABLE_TESTS!=y and CRYPTO=m:
+
+ lib/crypto/curve25519-selftest.o: In function `curve25519_selftest':
+ curve25519-selftest.c:(.init.text+0x60): undefined reference to `__crypto_memneq'
+ curve25519-selftest.c:(.init.text+0xec): undefined reference to `__crypto_memneq'
+ curve25519-selftest.c:(.init.text+0x114): undefined reference to `__crypto_memneq'
+ curve25519-selftest.c:(.init.text+0x154): undefined reference to `__crypto_memneq'

+Subject: USB: serial: option: add support for Cinterion MV31 with new baseline
+
+From: Slark Xiao <slark_xiao@163.com>
+
+commit 158f7585bfcea4aae0ad4128d032a80fec550df1 upstream.
+
+Adding support for Cinterion device MV31 with Qualcomm
+new baseline. Use different PIDs to separate it from
+previous base line products.
+All interfaces settings keep same as previous.
+
+Below is test evidence:

+
+For PID 00b8, interface 3 is GNSS port which don't use serial driver.
