[PATCH 0/6] Return -ENODEV instead of -EFAULT on module-get failure

[phucduc . bui]

From: bui duc phuc <phucduc.bui@xxxxxxxxx>

Hi all,

Several ALSA open/allocate paths call try_module_get() on the owning card
module and return -EFAULT when it fails. However, try_module_get() fails 
when the module is no longer live (i.e. it is going away), meaning the 
device is no longer usable.
This series updates only those paths, making the error code consistent
with the existing "device unavailable" checks in the same functions.
Other -EFAULT returns are left unchanged.
No functional change is intended.

Best regards, 
Phuc
