Subject: [PATCH v7 02/30] soc: fsl: cpm1: qmc: Fix __iomem addresses declaration
Date: Thu, 28 Sep 2023 09:06:20 +0200	[thread overview]
Message-ID: <20230928070652.330429-3-herve.codina@bootlin.com> (raw)
In-Reply-To: <20230928070652.330429-1-herve.codina@bootlin.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")
