firmware: qcom: scm: Return -EOPNOTSUPP for unsupported SHM bridge enabling
When enabling SHM bridge, QTEE returns 0 and sets error 4 in result to
qcom_scm for unsupported platforms. Currently, tzmem interprets this as
an unknown error rather than recognizing it as an unsupported platform.
Error log:
[ 0.177224] qcom_scm firmware:scm: error (____ptrval____): Failed to enable the TrustZone memory allocator
[ 0.177244] qcom_scm firmware:scm: probe with driver qcom_scm failed with error 4
To address this, modify the function call qcom_scm_shm_bridge_enable()
to remap result to indicate an unsupported error. This way, tzmem will
correctly identify it as an unsupported platform case instead of
reporting it as an error.
Fixes: 178e19c0df1b ("firmware: qcom: scm: add support for SHM bridge operations")
