[PATCH 03/15] staging: r8188eu: remove test code for efuse shadow map

Martin Kaiser
2021-11-13T18:55:49Z

The EFUSE_ShadowMapUpdate function has a parameter to replace the
actual read operations with test reads. The only caller of
EFUSE_ShadowMapUpdate does not use this test mode.

Remove the read test code from EFUSE_ShadowMapUpdate and the low-level
functions that it calls.
