[PATCH 09/14] phy: qcom: snps-femto-v2: check dev_read_addr_ptr() for NULL

[David Lechner]

Check the return value of dev_read_addr_ptr() for NULL instead of
IS_ERR(). This function only ever returns NULL on failure.

Add <errno.h>, since this is the first error code used directly
in this file.

Fixes: 968f512e6c9f ("phy: qcom: Add SNPS femto v2 USB HS phy")
