[PATCH v3 2/2] ALSA: core: Remove redundant variable and return the last statement

From: Meng Tang
Date: Mon Feb 28 2022 - 00:03:25 EST


Return the result from file->f_op->open() directly instead of
taking this in another redundant variable. Make the typical
return the last statement, return early and reduce the indentation
too.
