Subject: [PATCH v2] staging: r8188eu: Fix cast between incompatible function type
Date: Wed,  4 Aug 2021 16:32:18 +0200	[thread overview]
Message-ID: <20210804143218.13665-1-fmdefrancesco@gmail.com> (raw)

Fix sparse warnings of casts between incompatible function
types from ‘void (*)(void *)’ to ‘void (*)(long unsigned int)’
[-Wcast-function-type].

Suggested-by: Dan Carpenter <dan.carpenter@oracle.com>
Signed-off-by: Fabio M. De Francesco <fmdefrancesco@gmail.com>
---

v1 -> v2:
	According to a suggestion by Dan Carpenter, fix this issue by having
	functions to take an unsigned long instead of a pointer to void.
