fuse->base can not be unmapped if allocate lookups failed in tegra_init_fuse(), because it is an early_initcall, the driver will be loaded anyway and fuse->base will be accessed by other functions later, so remove the return -ENOMEM after allocating lookups failed to make less confusing.

soc/tegra: Changes for v5.11-rc1 This contains a couple of warning fixes and a fix for a mostly harmless bug in the process ID retrieval code. * tag 'tegra-for-5.11-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: soc/tegra: fuse: Fix index bug in get_process_id soc: tegra: fuse: speedo-tegra210: Remove a group of set but unused variables soc: tegra: fuse: speedo-tegra124: Remove some set but unused variables Link: https://lore.kernel.org/r/20201127144329.124891-2-thierry.reding@gmail.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>
This patch simply fixes a bug of referencing speedos[num] in every
for-loop iteration in get_process_id function.

The tegra_read_ram_code() is used by EMC drivers and we're going to make these driver modular, hence this function needs to be exported.
