Wei Yongjun 36164db278 nvmem: rmem: Fix return value check in rmem_read() ...

[ Upstream commit 58e92c4a49 ]

In case of error, the function memremap() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.

Fixes: 5a3fa75a4d ("nvmem: Add driver to expose reserved memory as nvmem")
