Subject: [PATCH v4 02/28] soc: fsl: cpm1: qmc: Fix __iomem addresses declaration
From: Herve Codina <herve.codina@...tlin.com>
Running sparse (make C=1) on qmc.c raises a lot of warning such as:
...
warning: incorrect type in assignment (different address spaces)
expected struct cpm_buf_desc [usertype] *[noderef] __iomem bd
got struct cpm_buf_desc [noderef] [usertype] __iomem *txbd_free
...
Indeed, some variable were declared 'type *__iomem var' instead of
'type __iomem *var'.
Use the correct declaration to remove these warnings.
Fixes: 3178d58e0b97 ("soc: fsl: cpm1: Add support for QMC")
