[PATCH v2] i2c: cadence: fixup of wait_for_completion_timeout return handling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



return type of wait_for_completion_timeout is unsigned long not int. The
return variable is renamed to reflect its use and the type adjusted to
unsigned long.

Signed-off-by: Nicholas Mc Guire <hofrat@xxxxxxxxx>

v2: int ret is an idiom not only a declaration - thus rather than just
    changing the type, rename the variable, as suggested by Wolfram Sang 
    <wsa@xxxxxxxxxxxxx>. 

Patch was only compile tested with multi_v7_defconfig
(implies CONFIG_I2C_CADENCE=y)

Patch is against 3.19.0-rc7 (localversion-next is -next-20150209)
