Subject: Input: jornada720_kbd - switch to devm_* APIs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a8a7bdc598ec0c355491bc1cac75f8f6b8a1740d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Input: jornada720_kbd - switch to devm_* APIs

Switch the jornada720_kbd driver to use the devm_* APIs.  This is in
preparation to removing the mach/irqs.h include from this driver.
