[PATCH] drivers: mmc: Mark the function sdhci_disable_irq_wakeups() as static in sdhci.c

[Rashika Kheria]

This patch marks the function sdhci_disable_irq_wakeups() as static in
host/sdhci.c because it is not used outside this file.

Thus, it also eliminates the following warning in host/sdhci.c:
drivers/mmc/host/sdhci.c:2553:6: warning: no previous prototype for ‘sdhci_disable_irq_wakeups’ [-Wmissing-prototypes]

This function has an EXPORT_SYMBOL_GPL, making it available for use
elsewhere in the kernel.  However, nothing in the kernel actually
*calls* this function, other than the one internal call in
sdhci_resume_host.  Thus, I'd suggest making this function static as you
have in this patch, and additionally deleting the EXPORT_SYMBOL_GPL for
it.

With that change:

[PATCH v2] drivers: mmc: Mark the function sdhci_disable_irq_wakeups() as static in sdhci.c

[Rashika Kheria]

This patch marks the function sdhci_disable_irq_wakeups() as static in
host/sdhci.c because it is not used outside this file. It also removes
the EXPORT_SYMBOL_GPL because no other file in kernel uses this
function.

Thus, it also eliminates the following warning in host/sdhci.c:
drivers/mmc/host/sdhci.c:2553:6: warning: no previous prototype for ‘sdhci_disable_irq_wakeups’ [-Wmissing-prototypes]
